Build your own Serverless Functions

Here’s how you can build your very own first serverless functions or if you wish to try another approach other than AWS Lambdas and/or Azure Functions.

- TL;DR

• Serve simple applications using serverless architecture provided by Vercel (former Zeit) following the documentation.
• Choose your language as follows. I myself chose Node.js (with TypeScript).

- Supported Languages

• Node.js
• Go
• Python
• Ruby

- Setup your first endpoint

import { NowRequest, NowResponse } from '@vercel/node'

export default (request: NowRequest, response: NowResponse) => {
  const { name = 'World' } = request.query
  response.status(200).send(`Hello ${name}!`)
}

• Vercel’s Serverless Functions follows this simple convention: put your endpoint file under the folder /api and it is all set. e.g. endpointname.ts => /endpointname

- How do I serve it at Vercel?

• You could download Vercel’s examples repository and cut your slack from it or just start your very own git (GitHub recommended) managed project.
• After you have logged in Vercel’s system, you can import your previously created project.

One could also just import from a template

• From now on it is pretty much done. Just make your adjustments such as environmental variables, NPM scripts, root folder, setup your domain and setup your branch deployment trigger.

- Integrations

• Vercel also provides a bunch of incredible integrations such as analytics and monitoring tools, which you can mostly use free of charge.

- Bonus

• There is also another incredible serverless tool for cache management (Redis), that is, lambda.store. Wait, what? Serverless Redis? Read more at Serverless Model
