freeCodeCamp Back End Development and APIs curriculum

build the final 5 APIs projects but using PHP/Laravel

Timestamp Microservice

• A request to /api/:date? with a valid date should return a JSON object with a unix key that is a Unix timestamp of the input date in milliseconds (as type Number)

• A request to /api/:date? with a valid date should return a JSON object with a utc key that is a string of the input date in the format: Thu, 01 Jan 1970 00:00:00 GMT

• A request to /api/1451001600000 should return {unix: 1451001600000, utc: "Fri, 25 Dec 2015 00:00:00 GMT" }

• Your project can handle dates that can be successfully parsed by new Date(date_string)

• If the input date string is invalid, the API returns an object having the structure { error :"Invalid Date" }

• An empty date parameter should return the current time in a JSON object with a unix key

• An empty date parameter should return the current time in a JSON object with a utc key

Request Header Parser Microservice

• A request to /api/whoami should return a JSON object with your IP address in the ipaddress key.

• A request to /api/whoami should return a JSON object with your preferred language in the language key.

URL Shortener Microservice

• You can POST a URL to /api/shorturl and get a JSON response with original_url and short_url properties. Here's an example: { original_url : 'https://freeCodeCamp.org', short_url : 1}

• When you visit /api/shorturl/short_url>, you will be redirected to the original URL.

• If you pass an invalid URL that doesn't follow the valid http://www.example.com format, the JSON response will contain { error: 'invalid url' }

Exercise Tracker

• You can POST to /api/users with form data username to create a new user.

• The returned response from POST /api/users with form data username will be an object with username and _id properties.

• You can make a GET request to /api/users to get a list of all users.

• The GET request to /api/users returns an array.

• Each element in the array returned from GET /api/users is an object literal containing a user's username and _id.

• You can POST to /api/users/:_id/exercises with form data description, duration, and optionally date. If no date is supplied, the current date will be used.

• The response returned from POST /api/users/:_id/exercises will be the user object with the exercise fields added.

• You can make a GET request to /api/users/:_id/logs to retrieve a full exercise log of any user.

• A request to a user's log GET /api/users/:_id/logs returns a user object with a count property representing the number of exercises that belong to that user.

• A GET request to /api/users/:_id/logs will return the user object with a log array of all the exercises added.

• Each item in the log array that is returned from GET /api/users/:_id/logs is an object that should have a description, duration, and date properties.

• The description property of any object in the log array that is returned from GET /api/users/:_id/logs should be a string.

• The duration property of any object in the log array that is returned from GET /api/users/:_id/logs should be a number.

• The date property of any object in the log array that is returned from GET /api/users/:_id/logs should be a string. Use the dateString format of the Date API.

• You can add from, to and limit parameters to a GET /api/users/:_id/logs request to retrieve part of the log of any user. from and to are dates in yyyy-mm-dd format. limit is an integer of how many logs to send back.
