how to run function before deploy

I want to test my nodejs funtion before I deploy it to git. Im using V1.4.2 and node-18.

How I can run the function to test the functionality?

TL;DR

To run a function before deployment, you can follow these steps: 1. Create a file called 'local-test.mjs' in the '/src' directory. 2. In 'local-test.mjs', import the main function that you want to test from 'main.js' (assuming it's in the same directory). 3. Install the 'dotenv' package and import it into 'local-test.mjs'. This will allow you to load environment variables. 4. Simulate the req and res objects, which represent the request and response objects. 5. Set up console.log and console.error functions for logging purposes. 6. Execute the main

It's easiest to just deploy it to Appwrite. You can deploy to a local Appwrite instance. Or, you can deploy to your prod project but with a different function Id.

Technically, it's also possible to run the open Runtimes container yourself: https://github.com/open-runtimes/open-runtimes/tree/main/runtimes/node-18.0#usage

I find an another way to do it. Simple and fast:

create a file like local-test.mjs in /src
With the content content:

TypeScript

// local-test.mjs
import main from './main.js'; // Assuming 'main.js' is in the same directory
import dotenv from 'dotenv';
dotenv.config();

// Simulate the req and res objects
const req = {
  method: 'GET', // Change this to 'POST' if needed
};

const res = {
  send: (data) => {
    console.log(data);
  },
  json: (data) => {
    console.log(JSON.stringify(data, null, 2));
  },
};

const log = console.log;
const error = console.error;

// Execute the main script
main({ req, res, log, error });

Start it with the command:

TypeScript

node --experimental-modules src/local-test.mjs

Now, you have the respnse, logs, errors, etc like in appwrite console 🙂

You may run into problems where it works locally, but not in Appwrite. I always feel like working incrementally and deploying to Appwrite is the best approach to make sure things work.

Of corse, but during devolopment its not so good deploy always to appwrite to test only 1 change. Its take to much time. Therefore Im looking something to test localy.
