Simple OAuth2 Reddit
This library is a wrapper around Simple OAuth2 Library
Specially made for Authorization Code Flow with Reddit.
Requirements
Latest Node 8 LTS or newer versions.
Getting started
npm install --save simple-oauth2 @jimmycode/simple-oauth2-reddit
or
yarn add simple-oauth2 @jimmycode/simple-oauth2-reddit
Usage
const simpleOAuth2Reddit = require('@jimmycode/simple-oauth2-reddit');
const reddit = simpleOAuth2Reddit.create(options);
reddit
object exposes 3 keys:
- authorize: Middleware to request user's authorization.
- getToken: Middleware for callback processing and exchange the authorization token for an
access_token
- oauth2: The underlying simple-oauth2 instance.

Example
Original boilerplate
const oauth2 = require('simple-oauth2').create({
client: {
id: process.env.REDDIT_APP_ID,
secret: process.env.REDDIT_APP_SECRET
},
auth: {
authorizeHost: 'https://www.reddit.com'
authorizePath: '/api/v1/authorize',
tokenHost: 'https://www.reddit.com',
tokenPath: '/api/v1/access_token'
}
});
router.get('/auth/reddit', (req, res) => {
const authorizationUri = oauth2.authorizationCode.authorizeURL({
redirect_uri: 'http://localhost:3000/auth/reddit/callback',
scope: ['identity'],
state: 'random-unique-string'
});
res.redirect(authorizationUri);
});
router.get('/auth/reddit/callback', async(req, res) => {
const code = req.query.code;
const options = {
code,
state: 'same-random-unique-string',
redirect_uri: 'http://localhost:3000/auth/reddit/callback'
};
try {
// The resulting token.
const result = await oauth2.authorizationCode.getToken(options);
// Exchange for the access token.
const token = oauth2.accessToken.create(result);
return res.status(200).json(token);
} catch (error) {
console.error('Access Token Error', error.message);
return res.status(500).json('Authentication failed');
}
});
With SimpleOAuth2Reddit
const simpleOAuth2Reddit = require('@jimmycode/simple-oauth2-reddit');
const reddit = simpleOAuth2Reddit.create({
clientId: process.env.REDDIT_APP_ID,
clientSecret: process.env.REDDIT_APP_SECRET,
callbackURL: 'http://localhost:3000/auth/reddit/callback',
state: 'random-unique-string'
});
// Ask the user to authorize.
router.get('/auth/reddit', reddit.authorize);
// Exchange the token for the access token.
router.get('/auth/reddit/callback', reddit.accessToken, (req, res) => {
return res.status(200).json(req.token);
});
