twitter-server

Provides easy Twitter integration.

Connects to the Twitter API using OAuth2 and exposes basic endpoints to retrieve tweets and users.

All endpoints returns JSON.

Exposed endpoints

/tweets/:username returns tweets for requested Twitter user

/tweets/:username/media returns tweets with media for requested Twitter user

/user/:username returns requested Twitter user

Cache

Twitter responses are cached by default.

Adjust cache TTL by setting the desired values in your config file.

These are the default values expressed in minutes:

"cacheTtl": {
  "users": 15,
  "tweets": 2
}

Set a value of 0 to disable cache for an endpoint.

CORS

By default all domains are allowed. You can setup CORS whitelisting by adding this to your config file to avoid responding to not allowed domains:

"cors": {
  "whitelist": ["http://your-domain.com"]
}

Setup

Make a copy of src/config.json and set your Twitter credentials by replacing key and secret with your app's data.

While signed in to Twitter open your Twitter apps page and grab the required data from there.

You will provide this config file when starting twitter-server.

Sample config:

{
  "cors": {
    "whitelist": []
  },
  "twitter": {
    "key": null,
    "secret": null
  },
  "tweetsPerRequest": 70,
  "ip": "127.0.0.1",
  "port": "3080",
  "cacheTtl": {
    "users": 15,
    "tweets": 2
  }
}

Install

Using git:

git clone https://github.com/codealchemist/twitter-server

Using npm:

npm install twitter-server --save

Or globally if you like:

npm install twitter-server --global

To always run it before your app you can have something like this on your package.json:

  "scripts": {
    "start": "node node_modules/twitter-server/src/index.js --config twitter-server-config.json && node src/index.js"
  }

Being src/index.js the entry point of your app and twitter-server-config.json your custom config for twitter-server located at the root of your project.

Then you can start your app with npm start and, first, it will start twitter-server.

Start

In mocked mode, without the need to provide Twitter credentials, it will return mocked responses, useful for integration testing:

npm start

If you already created a config file with your Twitter credentials then:

npm start -- --config my-config.json

Or:

node src/index.js --config my-config.json

Test

npm test

It will check:

• your code doesn't have errors and matches standard styling
• there are not unused, outdated or missing packages using npm-check
• methods do what they are expected to do using mocha and chai

Continuous development test

npm run test-watch

This will run unit tests only, continually watching for file changes.

Notes

Requires node above v4.1. If your current node version doesn't support destructuring you'll need to add the following flag after the node command:

--harmony_destructuring

You'll need to add this to package.json in the scripts section to the start entry, or in the command line if you directly run the app with node, example:

node --harmony_destructuring src/index.js
