realworld-api

RealWorld library for open API calls using JavaScript

about

RealWorld is a fullstack Medium clone that can be written using many different web frameworks. It was developed as a way to show how to accomplish the same website using different backend and frontend technologies.

I created this module as a simple way to interact with the RealWorld API Specification which could be easily dropped in to any frontend technology stack.

Each public function is well-documented in the code using JSDoc and the documentation can be automatically generated using documentation.js.

Unit tests are written to be isolated and idempotent. Addtionally, you do not have to be connected to the internet in order to run the tests. The tests run on an ephemeral local Node.js HTTP server and ensure the API requests are correct.

realworld-api mostly follows the logic of the Tiny Guide to Non Fancy Node, however it makes use of template literals from ES6. If you are bundling realworld-api for use in an older browser that doesn't support template literals, you may want to compile your code using Babel or use a browserify transform such as ES2020.

RealWorld~requestCallback

This callback is displayed as part of the RealWorld class. The error should be null if the method was able to run. HTTP and API errors are not caught as errors so that you can catch them yourself. For example, a response code 500 may return (null, { res.statusCode: 500, res.statusMessage: 'Internal Server Error' }, null).

API errors are returned with a 422 status code. Errors are included as JSON in the data result and are in the form of

{ "errors":{ "body": [ "can't be empty" ] } }

where body may be any parameter such as password, email, etc.

Successful API requests will return JSON data as seen in the RealWorld API Spec

Type: Function

Parameters

• err Error error if method was unable to run
• res Object response object from server
• data Object data result from the server as JSON

Examples

function handleResponse (err, res, data) {
  if (err) return console.error(err)
  if (res.statusCode === 422 && data.errors) {
    Object.keys(data.errors).forEach(function (err) {
      var values = data.errors[err]
      values.forEach(function (v) {
        console.error(`${err} ${v}`)
      })
    })
    return
  }
  if (res.statusCode !== 200) {
    return console.log(`${res.statusCode}: ${res.statusMessage}`)
  }
  return console.log(data)
}
