How to get Twitter User info using Twitter API in a Netlify Functions
Posted on October 3, 2021
Interacting with the Twitter API with Node.js is pretty simple thanks to the twitter library.
After you've activated your Developer Account and created a project with the generated credentials, it's just a matter of wrapping some code in a Netlify function:
const Twitter = require('twitter')
const client = new Twitter({
consumer_key: process.env.TWITTER_CONSUMER_KEY,
consumer_secret: process.env.TWITTER_CONSUMER_SECRET,
access_token_key: process.env.TWITTER_ACCESS_TOKEN_KEY,
access_token_secret: process.env.TWITTER_ACCESS_TOKEN_SECRET
})
exports.handler = async (event, context) => {
const body = JSON.parse(event.body)
const screen_name = body.screen_name
// check if the required param is present
if (!screen_name) {
return {
statusCode: 200,
body: JSON.stringify({ error: true, message: 'Missing screen_name' })
}
}
// fetch the API
const res = await client.get('users/show', { screen_name })
// return the result
return {
headers,
statusCode: 200,
body: JSON.stringify(res)
}
}
The above function require a POST request. I should add a guard of the httpMethod.
