If you are trying to use the Twitter API, you probably saw many examples using the twitter-api-v2 npm package which works fine in Node.js but unfortunately does not work in a Cloudflare Worker as it relies on Node.js APIs.
In order to use the Twitter API, you have to handle the OAuth authentication and use fetch to send the request. At the time I wrote this post there were no examples of this, so it took me some time to figure out how to do it. The following snippet shows you how to send a tweet, but you can use any API method you want.
import OAuth from 'oauth-1.0a';
import { HmacSHA1, enc } from 'crypto-js';
const oauth = new OAuth({
consumer: { key: TWITTER_API_KEY, secret: TWITTER_API_SECRET },
signature_method: 'HMAC-SHA1',
hash_function(baseString, key) {
return HmacSHA1(baseString, key).toString(enc.Base64);
},
});
const oauthToken = {
key: TWITTER_ACCESS_TOKEN,
secret: TWITTER_ACCESS_TOKEN_SECRET,
};
const requestData = {
url: 'https://api.twitter.com/1.1/statuses/update.json',
method: 'POST',
data: { status: 'Hello from Cloudflare worker' },
};
const response = await fetch(requestData.url, {
method: requestData.method,
headers: {
...oauth.toHeader(oauth.authorize(requestData, oauthToken)),
'Content-Type': 'application/x-www-form-urlencoded',
},
body: new URLSearchParams(requestData.data),
});
console.log(await response.json());
