Functions: Added support for Node.js 20

Today we are happy to announce you can now chose whether you want to use Node.js 18 or Node.js 20 as your functions runtime.

Doing so is very easy, just select your preferred version in your nhost.toml. For instance, imagine you have the following function in your project


_12// functions/echo.ts
_12import { Request, Response } from 'express'
_12import process from 'process'
_12
_12export default (req: Request, res: Response) => {
_12  res.status(201).json({
_12    headers: req.headers,
_12    query: req.query,
_12    node: process.version, // return node version
_12    arch: process.arch,
_12  })
_12}

We can use Node.js 18 by ensuring the following configuration is in our nhost.toml:


_10[functions.node]
_10version = 18

If we now start the CLI with nhost up or push to our deployment branch we should be able to verify the runtime by invoking the function:


_10$ curl -s https://local.functions.nhost.run/v1/echo | jq .node
_10"v18.20.3"

To use Node.js 20, just set the correct version:


_10[functions.node]
_10version = 20

And invoke the function again:


_10$ curl -s https://local.functions.nhost.run/v1/echo | jq .node
_10"v20.15.0"

While a small improvement, we hope this new addition will help you homogenize your runtime environments and simplify your setups.
