Lambda for simply sending a tweet upon post using Netlify's Functions capabilities.

• Deploy to Netlify (use button above)
• Add a unique key as your APP_SECRET under Settings > Build & Deploy > Environment
• Once deployed, you're ready to get started!

Your function should now be avialable at:

https://[your-netlify-site].netlify.com/.netlify/functions/tweet

When posting to the endpoint, you'll need to generate a JWT given the same APP_SECRET as above. The contents of the JWT before signed should look like:

{
  twitter_consumer_key: [key],
  twitter_consumer_secret: [key],
  twitter_access_token_key: [key],
  twitter_access_token_secret: [key],
}

You can use libraries such as Auth0's JsonWebToken to generate within your app: https://github.com/auth0/node-jsonwebtoken

Pass this as an Authorization header

The body of the post should look like the following:

{
  "description": "[text of tweet]",
  "link": "[tweet link appended to status]",
  "image": "[tweet image (optional)]",
}

To begin setup, with a newly cloned repo:

yarn install

Create a local .env file at the root of the project with the shared secret. This is used in coordination with JWT to create token containing your Twitter keys that gets posted to this function endpoint.

APP_SECRET="[secret]"

To test this locally, run:

yarn serve

The function should now be available at localhost:9000/tweet
