821579,Node.js Express: Find Recipe Step,fullstack,"Your company is creating a new Recipe Management app . As the NodeJS developer in the company , you have been given the task to write a basic Express app that has a single route for fetching a single recipe's current step-index based on the elapsedTime passed as input . The request to the route /recipes/step/:id ? elapsedTime returns the index of the current step of the recipe based on the elapsed time in the format {""""index: currentIndex}. If the ID passed in the URL is missing or is not a valid number , the server should respond with the status code 400 and the string message NOTFOUND in the body of the response . If the elapsedTime query parameter is not present in the URL , it should default to 0. Note: Elapsed time should be interpreted as a Number , and the unit of measurement is the same as the unit of measurement for the timers (i . e ., minutes). Each Recipe object has a list of steps , stored in the steps property , and the corresponding timers , stored in the timers property . The steps and timers are two different arrays , but they are interpreted in combination with each other .

823438,Node.js Express: Dynamic Router,fullstack,"Your company wants to create a new routing framework based on ExpressJS that allows developers to perform file-based routing . A new route can be simply added to the app by creating a new file in the pages folder . The framework reads the pages directory and generates a set of dynamic routes that can be added to Express routing . Consider the pages directory with the following files: - pages -- index . html -- product --- index . html --- slug . html --- product1. html The corresponding generated Express routes should be: Method Route Served File GET / /pages/index . html GET /product/product1 /pages/product/product1. html GET /product/:slug /pages/product/slug . html GET /product /pages/product/index . html Each sub-directory in the pages directory becomes a separate path in the dynamically generated URL . So the product subdirectory generates the route /product . The index . html file of each directory becomes the base HTML file for the route . To generate a route with URL parameters , create the file prefixed with an underscore , like so: /pages/product/slug . html -> product/:slug The module resolver . js is responsible for converting the file structure to the corresponding URL routes . The module should return a Promise as the default export . The Promise should resolve with an array of routes in the following format: [ { """"url"""": """"/"""", """"file"""": """"/index . html"""" }, { """"url"""": """"/product"""", """"file"""": """"/product/index . html"""" }, { """"url"""": """"/product/:slug"""", """"file"""": """"/product/slug . html"""" } ] The program must read the directory pages and generate the URLs .

906396,NodeJS: Analytics Ingestion API,fullstack,"In this challenge , your task is to implement a simple REST API to manage a collection of the high-volume event streams . Each event is a JSON entry with the following keys: id : The unique entry ID . (Integer) eventType : The type of event data entry . Can be one of 'click' or 'pageView'. (String) user : The unique user ID .(Integer) date : The date when the event occurred(Date) Here is an example of an event JSON object: { """"id"""": 1, """"eventType"""": """"click"""", """"user"""": 1, """"date"""": """"2020-08-29T08:48:48.737Z"""" } The model implementation is provided and read-only . The task is to implement the REST service that exposes the /analytics endpoint , which allows for ingesting and querying the collection of event records in the following way: POST request to /analytics : creates a set of events serially expects a JSON array containing a series of user eventswithout the id and the date properties as thebody payload . Each object in the JSON array must be validated before saving based on the below-mentioned criteria . each list of the events can contain duplicate entries for auser and the event type . Every event objectin the listshould fulfilthe following criteriain order to be saved into the systemto avoid duplicates: a user can have only one 'click' event type in a 3-second window . All other 'click' events for the same user in the window should be discarded . a user can have only one 'pageView' event type in a 5-secondwindow . All other 'pageView' events for the same user in the window should be discarded . adds the given event object to the collection of events and assigns a unique integer id to it . The first created event must have id as 1, the second one has id as 2, and so on . adds the date property equal to the current system date to each saved object . the response code is 201, and the response body is a JSON containing the total number of events that were successfully ingested . Sample is : {""""ingested"""" : 4} HINT: In order to find an event in a n-second window from current time T , you can use the [Op . gte] operator of sequelize with the value set to the (T-n) seconds . { date: { [Op . gte] : VALUE} } //Where value is T - n seconds NOTE: A utility function subtractSecondsFromCurrentTime is provided in the utils . js file which accepts the seconds to subtract from the current time and returns the javascript date object for the time (T-n) GET request to /analytics : return a collection of all events the response code is 200, and the response body is an array of all events in any sort order DELETE , PUT , PATCH request to /analytics/<id> : the response code is 405 because the API does not allow deletingor modifying events for any id value You should complete the given project so that it passes all the test cases when running the provided unit tests .

907914,NodeJS: Medical Records Module,fullstack,"As a NodeJS developer in your company , you have been given the responsibility to create a medical records manager module that fetches the records from an external API and uses these records to provide insights within the time limits specified . Implement the module records . js such that it has the following set of functionalities: The file should export a class MedicalRecords as the default export of the module , and it should inherit from the EventEmitter class . The class should have the following methods: constructor : Fetches the records from an API and getsthe list of paginated medical records . TheURL is ' https://jsonmock . hackerrank . com/api/medicalrecords ? page=[PAGE]' where PAGE is the numeric page number to fetch the paginated data from the API . When all the records are fetched from the API for all the pages , the class should emit the 'INITIALISED' event with no data requirements for the payload to be passed to the callback . The date from the API contains a list of medical records which are then used to provide insights . The responsehas the following format: { page: 1, perpage: 10, total: 1, totalpages: 1, data: [ // Data contains the list of medical records { id: 11, timestamp: 1563846626267, diagnosis: { id: 2, name: """"Common Cold"""", severity: 1 }, vitals: { bloodPressureDiastole: 126, bloodPressureSystole: 75, pulse: 99, breathingRate: 22, bodyTemperature: 101.9 }, doctor: { id: 2, name: """"Dr Arnold Bullock"""" }, userId: 3, userName: """"Helena Fernandez"""", userDob: """"23-12-1987"""", meta: { height: 157, weight: 108 } ... }, ] } page : The current page number of the response (Number) perpage : The total number of items in a single page . This property is immutable . (Number) total : The total number of medicalrecords matching the filter criteria (Number) totalpages : The total number of pages containing the results for the filter criteria(Number) data : The Array containing a list of records (Array of objects) getAveragePulseForUser : Accepts a numeric userId as an argument and returns the average pulse for the user as a float value synchronously . From the fetched records , use matching userId property to get the records for a particular user and useproperty 'vitals . pulse' for each record to calculate the avergae . getDiagnosedDiseaseNamesForDoctor : Accepts a numeric doctor ID as an argument and returns the unique disease names , synchronously , diagnosed by the doctor as a string separated by ',' in the order , they appear in the records . Use matching doctor . id to get the records for a particular doctor and use property 'diagnosis . name' property to calculate unique diseases . The file index . js is present with an example implementation of this class and can be used to validate if the class works as expected . The Example output of this file is mentioned below . Pages of the paginated APIs can be accessed by modifying the page value in the request . Eg: https://jsonmock . hackerrank . com/api/medicalrecords ? page=2 to fetch record for page number 2. You should complete the given project so that it passes all the test cases when running the provided unit tests . You are free to use any package make API requests . For convenience , the project already includes the axios package to make API calls .

907933,ExpressJS: Authorization Middleware,fullstack,"Your company is launching a task manager app soon . The team has already created an ExpressJS app with several routes for creating and managing tasks . As the NodeJS developer in your company , you are required to write an Authorization middleware to provide access to some routes based on the role of the user . The middleware should implement the following functionalities: Complete the middleware . js module . The module's default export is an Express JS middleware function . This function should parse the 'x-role' header and check whether the role has access to the route or not . The scope of the route is passed to the middleware as a string in the format <SCOPENAME>.<ACTIONNAME> Example: To check if the user has access to the create a task (in the tasks route), the scope passed to the middleware will be """"tasks . create"""", where """"tasks"""" is the scope name and """"create"""" is the action name separated by a """"."""" dot . The roles-scopes mapping is stored in a file named roles . txt. The data is stored as a JSON string . The structure of each role-scope mapping object is as follows: { """"role"""": """"admin"""", """"scopes"""": { """"tasks"""": [ """"create"""", """"getById"""" ] } } role: This is the property which has to match with the x-role header value passed with the request . [STRING] scopes: An object containing key-value pairs corresponding to each SCOPENAME of the system . If the passed scope name does not match with any of the keys defined in the object , the access is invalid and the server should respondback with the status code 403 while not passing the control to the next function . [OBJECT] [scopeName]: Each dynamic key in the scopes object is a list of valid actions the user has access to in the current scope . [STRING ARRAY] If the role passed in the x-role header is not present in the roles JSON , it does not have access and the server should respondback with the status code 403 while not passing the control to the next function . If the role has access to the route , pass the control to the next function in the middleware stack . Complete the tasks . js module to include all the routes with the appropriate middleware mapping mentioned below . HINT: Make sure to trim the extra whitespaces from the JSON string before parsing it . Test Requirements The middleware functionshould be written in the file middleware . js , and the function should be the default export of the file .

909065,NodeJS: API Aggregator Service,fullstack,"In this challenge , your task is to implement an ExpressJS based API Aggregator service . The goal to communicate with various APIs , accumulate the responses and return a consolidated transformed response . The app accepts a single request to the endpoint /users/:userName . The response to be returned should be fetched from 2 different API sources detailed as follows: 1. User Details The user details should be fetched from the API https://jsonmock . hackerrank . com/api/articleusers ? username=<USERNAME> where <USERNAME> is the parameter passed to the request . The response from the external API is a JSON object having the following structure: { page: 1, perpage: 10, total: 1, totalpages: 1, data: [ // Data contains the list of users matching the username . If the data for the username is present , the array will contain only one object . { """"id"""": 1, """"username"""": """"epaga"""", ... } ] } If the username passed to the request does not exist in the external system , the data array will be empty . In such a scenario , the local API should respond with a status code of 404 with the response body having the text as """"Username Not Found"""". 2. User Transactions If the user details is successfully fetched from the First API , use the ID property of the details object(received in above API call) to fetch the paginated transactions for the user . The API to fetch the list of paginated transactions is https://jsonmock . hackerrank . com/api/transactions ? page=<PAGE>&userId=<USERID> where <PAGE> is the numeric page number to fetch the paginated data from the API and the <USERID> should match with the ID property fetched from the First API . The response from the transactions API has the following format: { page: 1, perpage: 10, total: 1, totalpages: 1, data: [ // Data contains the list of user transaction matching the user ID . { """"id"""": 8, """"userId"""": 4, """"userName"""": """"Francesco De Mello"""", """"timestamp"""": 1548805761859, """"txnType"""": """"credit"""", """"amount"""": """"1,214.44"""", ... } ] } The response structure from the second API can be described as follows: page : The current page number of the response (Number) perpage : The total number of items in a single page . This property is immutable . (Number) total : The total number of transactions matching the filter criteria (Number) totalpages : The total number of pages containing the results for the filter criteria(Number) data : The Array containing a list of transactions matching the filter criteria (Array of objects) Further pages of the paginated APIs can be accessed by modifying the page value in the request . Eg: https://jsonmock . hackerrank . com/api/transactions ? page=2&userId=<USERID> Using the responses from both the API sources , a new transformed response has to be constructed and returned back in the response body . Here is an example of the final response object: { """"user"""": { """"id"""": 6, """"username"""": """"saintamh"""", """"about"""": """""""", """"submitted"""": 71, """"updatedat"""": """"2019-09-06T11:13:29.000Z"""", """"submissioncount"""": 51, """"commentcount"""": 15, """"createdat"""": 1510174513 }, """"totalTransactions"""": 67, """"summary"""": [ { """"id"""": 8, """"userId"""": 6, """"userName"""": """"Francesco De Mello"""", """"timestamp"""": 1548805761859, """"txnType"""": """"credit"""", """"amount"""": """"1,214.44"""", """"location"""": { """"id"""": 1, """"address"""": """"948, Entroflex , Franklin Avenue"""", """"city"""": """"Ilchester"""", """"zipCode"""": 84181 }, """"ip"""": """"35.151.1.82"""" } ] } The response structure can be described as follows: user : The user details object fetched from the first API source(User) totalTransactions : The overall number of transactions for the user fetched from the second API(Number) summary : Only the first 3 transactions for the user fetched from the second API . Should be a blank array if there are no transactions for the user(Transactions Array) The task is to implement the REST service that exposes the /users/:userName endpoint . You should complete the given project so that it passes all the test cases when running the provided unit tests . The project includes the following npm packages pre-installed through npm .

909381,NodeJS: Parking Spot,fullstack,"As a NodeJS developer in your company , you have been given the responsibility to create an application that maintains the Car Parking Slots of the company . Implement the module parking . js such that the application has following set of functionalities: The file should export a class Parking as the default export of the module , and it should inherit from the EventEmitter class . The constructor of the classinitialises thenumber of slots available which defaults to 5. Itoptionally accepts a parameter , anumber , and assigns number of slots using this value if itis passed . The constructor should initialise a list of size equivalent to the number of slots available , and if a car is not assigned to aslot at any point in time , the correspondingslot should have a null value in the list . The class should have the following methods: parkCar : Accepts an object having the property carNumber as a parameterand assigns this car to the first empty slot available . If no slots are available for parking , the class should emit a 'parkingfull' event , with an object having the property carNumber havingvalue same as the carNumber from parameter , sent as the payload to the callback function . Else , if the parking operation was successful , the class should emit a 'parkingstarted' event , with an object having the property carNumber havingvalue same as the carNumber from parameter , sent as the payload to the callback function Parameter to this function has following structure: { carNumber : 'CAR-3' (String or Number) } getList : Returns the current state of the slots . If a slot is not occupied , the corresponding index in the array should have a null value , else it should contain the car number of the vehicle . remove : Accepts a single parameter carNumber (string or number). If the vehicle having the same carNumber is parked in one of the slots , removes its assignment from the list and reallocatenull value to the slot which just became empty . If the car is removed from the parking , the class should emit a 'parkingremoved' event , with an object having the property carNumber havingvalue same as the carNumber from parameter , sent as the payload to the callback function . Else if , no matching cars are parked with the carNumber passed , the class should emit a 'invalidnumber' event , with an object having the property carNumber havingvalue same as the carNumber from parameter , sent as the payload to the callback function NOTE: You can assume that the carNumber passed to the parkCar function is always unique and you do not have handle this scenario .

909946,NodeJS: Rate Limiter Middleware,fullstack,"As the NodeJS developer in your company , you are required to write an ExpressJS Rate Limiting middleware to throttle the API traffic for the app to make sure that the app runs at full efficiency . The middleware should implement the following functionalities: Implement the rate-limiter . js middleware module . The module should export the class RateLimiter by default . This class must have a method named 'apply' which acts as the express middleware function . This class has 2 member variables , 'limit', and 'windowMs'. The significance of these members are described below: windowMs : The period of time in which an IP address can hit a particular number of requests (numeric window size in milliseconds). [Number] limit : The number of requests each IP address can hit in a period of time defined by the 'windowMs' parameter . The default value for limit property is 5 and the default value for windowMs is 1000 milliseconds . This translates to the Rate Limit of 5 request per second per IP address . Rate Limit Example: 20 requests per 5 seconds per IP Address | | limit windowMs (5000 milliseconds) The classoptionally accepts an object containing the properties , 'limit', and 'windowMs'. If it is present , use this object to assign the values to members ' windowMs' and 'limit'. (Or else use default values). This middleware should be initialized and the apply methods should be stacked to the GET '/tasks' route of the app to make sure that the number of requests to this route for a user by their IP address is within the limits specified . If the current request has crossed the limits specified , the server should return the response with the status code 429 with no particular requirement on the response body . In this case , the control should not be passed to the next function of the middleware . If the current request is valid and within the limits specified , a header 'x-limit-remaining' should be added to the response with the value as the number of requests remaining before the limit in the current window is reached . The control should be passed to the next function . For a particular IP address , when limit is reached in a window , for the request to go through again , difference between the current time and the time of thelast request that passed , should be greater than or equal to windowMs . The IP address for the request can be extracted from the 'req . ip' property of the request object passed to the middleware . For testing , the app has 'trust proxy' enabled and this the 'x-forwarded-for' header can be used to send a request using different IP addressed . The value of this header will be set as the 'req . ip' property of the request object . Note: Please make sure to properly set the context for the apply method which will be used as the middleware function . Test Requirements The middleware classshould be written in the file rate-limiter . js , and it should be the default export for the file . This class should have a method named apply which will be used as the middleware function . The function must call the next() function if the request is successful . Please use one of 'res . set' or 'res . setHeader' methods of the express to set the header in the response object . Please use the 'res . status' method chained with the 'send' method of the response object to return the response . res . status(STATUSCODE). send('YOURBODY'); Examples Let's look at some examples: Rate Limit: 4 Req/Sec Let's assume each request comes at 0.2 second intervals Window size: 1 second At 0.2 seconds , Req 1 ---------------------- IP : 192.168.0.1 Valid: No entry for this IP address exists yet and buffer is for 4 requests in 1 second . Response Header: x-limit-remaining = 3 As now only 3 more requests can be hit before the rate limit is reached At 0.4 seconds , Req 2 ---------------------- IP : 192.168.0.1 Valid: The entry for IP exists but its limit is 4 while this is only the 2nd request in this window . Response Header: x-limit-remaining = 2 At 0.6 seconds , Req 3 ---------------------- IP : 192.168.0.1 Valid: The entry for IP exists but its limit is 4 while this is only the 3rd request in this window . Response Header: x-limit-remaining = 1 At 0.8 seconds , Req 4 ---------------------- IP : 192.168.0.1 Valid: The entry for IP exists but its limit is 4 but this is the last request for this IP in this window . Response Header: x-limit-remaining = 0 At 1 seconds , Req 5 ---------------------- IP : 192.168.0.1 Invalid: The limit for this request has been reached . Response Status: 429 This IP address has to wait the equivalent of 1 unit of window size to get a valid response again . Thus the next valid request can only be sent for this IP 1 second later . At 1 seconds , Req 1 for different IP ---------------------- IP : 192.168.0.2 Valid: No entry for this IP address exists yet and buffer is for 4 requests in 1 second .

In TransactionApi , implement the getTransactions method to call a mock GET API to https://jsonmock . hackerrank . com/api/transactions/ which returns data in this shape: { """"page"""": 1, """"perpage"""": 10, """"total"""": 12, """"totalpages"""": 2, """"data"""": [ { """"id"""": 1, """"userId"""": 1, """"userName"""": """"Alex Oliver"""", """"timestamp"""": 1549536882071, """"txnType"""": """"debit"""", """"amount"""": """"1,670.57"""", """"location"""": { """"id"""": 7, """"address"""": """"770, Deepends , Stockton Street"""", """"city"""": """"Ripley"""", """"zipCode"""": 44139 }, """"ip"""": """"212.215.115.165"""" }, """"..."""" ] } Wrap the method in a try-catch block and return an empty list if any exception occurs . For the TransactionApi , add at least 3 testsin TransactionApiTest to prove the logic: Success Test to verify the response when the API returns data . Default data test to verify the response when the API returns empty data . Exception Test to verify the response when the APIthrows an exception . Implement a single method in the TransactionService service class which depends on the TransactionApi bean . It must have a single method getTransactions(). It callsthe TransactionApi method and returns the response as-is . Write at least 1 test in TransactionServiceTest to prove that an interaction happened with TransactionApi . Finally , theimplementation for create and get user are provided in UserService . Add at least 4 tests for each scenario: testCreateUserServiceWithNullInput - verify an exception when the input is null testCreateUserService - verify the user creation testGetUserServiceWithNullInput - verify an exception when the email is null testGetUserServicedbError - verify an exception when a database error occurs",https://istreet-proctor.s3.amazonaws.com/fullstack/questions/acg5h9limom/files/b1bdf1e367c7389f160ec64bbe91099e/project.zip,java_spring_boot,.eval/score.sh,"[{""file"": ""TEST-com.hackerrank.eval.FunctionalTests.xml"", ""name"": ""whenUserCreatedCorrectResponseReturned"", ""type"": ""junit"", ""weight"": 0.03125}, {""file"": ""TEST-com.hackerrank.eval.FunctionalTests.xml"", ""name"": ""whenRetrievingListOfUsersCorrectResponseReturned"", ""type"": ""junit"", ""weight"": 0.03125}, {""file"": ""TEST-com.hackerrank.eval.TestCoverageTests.xml"", ""name"": ""wroteAtLeastXNumberOfTests{int}[1]"", ""type"": ""junit"", ""weight"": 0.125}, {""file"": ""TEST-com.hackerrank.eval.TestCoverageTests.xml"", ""name"": ""wroteAtLeastXNumberOfTests{int}[2]"", ""type"": ""junit"", ""weight"": 0.125}, {""file"": ""TEST-com.hackerrank.eval.TestCoverageTests.xml"", ""name"": ""wroteAtLeastXNumberOfTests{int}[3]"", ""type"": ""junit"", ""weight"": 0.0625}, {""file"": ""TEST-com.hackerrank.eval.TestCoverageTests.xml"", ""name"": ""wroteAtLeastXNumberOfTests{int}[4]"", ""type"": ""junit"", ""weight"": 0.125}, {""file"": ""TEST-com.hackerrank.eval.TestCoverageTests.xml"", ""name"": ""wroteAtLeastXNumberOfTests{int}[5]"", ""type"": ""junit"", ""weight"": 0.0625}, {""file"": ""TEST-com.hackerrank.eval.TestCoverageTests.xml"", ""name"": ""wroteAtLeastXNumberOfTests{int}[6]"", ""type"": ""junit"", ""weight"": 0.0625}, {""file"": ""TEST-com.hackerrank.eval.TestCoverageTests.xml"", ""name"": ""wroteAtLeastXNumberOfTests{int}[7]"", ""type"": ""junit"", ""weight"": 0.125}, {""file"": ""TEST-com.hackerrank.eval.TestCoverageTests.xml"", ""name"": ""wroteAtLeastXNumberOfTests{int}[8]"", ""type"": ""junit"", ""weight"": 0.0625}, {""file"": ""TEST-com.hackerrank.eval.TestCoverageTests.xml"", ""name"": ""wroteAtLeastXNumberOfTests{int}[9]"", ""type"": ""junit"", ""weight"": 0.0625}, {""file"": ""TEST-com.hackerrank.eval.TestCoverageTests.xml"", ""name"": ""wroteAtLeastXNumberOfTests{int}[10]"", ""type"": ""junit"", ""weight"": 0.125}]","['TEST-com.hackerrank.eval.FunctionalTests.xml', 'TEST-com.hackerrank.eval.TestCoverageTests.xml']",12
1783520,NodeJS: Weighted Load Balancer,fullstack,"Implement a weighted load balancer that distributes incoming requests to a set of backend servers based on their weights . The load balancer should ensure that servers with higher weights receive more requests relative to their weights compared to servers with lower weights . An object with the following keys represents each server: name: The name of the server (String) weight: The weight of the server (Integer) The load balancer should distribute requests in a way that reflects these weights . Here is an example of a list of servers: [ { """"name"""": """"Server 1"""", """"weight"""": 1 }, { """"name"""": """"Server 2"""", """"weight"""": 2 }, { """"name"""": """"Server 3"""", """"weight"""": 3 } ] Function getNextServer : Expect a weightedServers array containing the server name and weight .
