feat: add nodejs 22 env

Node.js 22 Runtime Environment with ESM Support

Summary

This PR introduces a separate directory for Nodejs 22 runtime env (server.js) with some dependency updates such as Pino logging instead of Morgan.

Resolves #277

New Features

Node.js 22 Environment

• Dedicated directory: nodejs22/ with complete environment setup
• Latest Node.js: Version 22.17.1 on Alpine Linux 3.22
• ESM support: "type": "module" configuration enables native import/export syntax
• Modern dependencies: Express 5.1.0, Pino logging, WebSocket support

ESM-Ready Examples

All examples use modern ESM syntax and Node.js 22 features:

Example	Description	Node.js 22 Features
hello.js	ESM hello world	ESM module with query params
weather.js	HTTP requests demo	Native fetch API, error handling
multi-entry.js	Multiple endpoints	Named exports, routing
broadcast.js	WebSocket broadcasting	Multi-client messaging with ws 8.18
kubeEventsSlack.js	Kubernetes integration	Event processing, webhooks

Usage

Environment Creation

# Create Node.js 22 environment
fission env create --name node22 --image davidchase03/node-env-22:v2.0.1

# With builder support
fission env create --name node22 --image davidchase03/node-env-22:v2.0.1 --builder node-builder-22

Function Deployment (ESM)

# Deploy ESM function
fission fn create --name hello-esm --env node22 --code hello.js

# Test with query parameters
fission fn test --name hello-esm
curl "$FISSION_ROUTER/hello-esm?name=World"

Modern Function Syntax

// ESM function
export default async function(context) {
    const { query } = context.request;
    return {
        status: 200,
        body: JSON.stringify({
            message: `Hello ${query.name || 'World'} from Node.js 22! 🚀`,
            nodeVersion: process.version
        }),
        headers: { 'Content-Type': 'application/json' }
    }
}

Breaking Changes

None - this is purely additive. Existing nodejs/ environment remains unchanged for backward compatibility.

Testing

• All existing Node.js tests continue to pass
• New Node.js 22 specific test cases in nodejs22/test/
• ESM examples tested with Node.js 22.17.1 runtime

Benefits

• Modern JavaScript: Native ESM, top-level await, latest syntax
• Better Performance: Node.js 22 optimizations and faster startup
• Developer Experience: Modern tooling, better error messages
• Backward Compatible: Existing Node.js environment unaffected

Please add nodejs22 in

Also will need copy of this for node22 in workflow

ok i have resolved the feedback provided

[davidchase]

it seems like i needed to address the tests and gh actions but i dont see it running again since yesterday, how can i validate that the actions working properly again?

[davidchase]

@sanketsudake can you help me make sense of whats failing? because it seems like nodejs (current runtime and nodejs22 are failing in the actions but i had not made changes to nodejs directory at all

[sanketsudake]

I went through dump didnt find much as some of tools versions are outdated. Troubleshooting here #423 .
Will fix so that you can rebase.

[sanketsudake]

Got most of things updated and also switched default version to nodejs 22 via PR #423

I am seeing if we can have multiple versions under same env.
Eg. There ESM version and we also got request for bun #418

We can have nodejs image name and different tags.

ok i will wait for you to merge the PR so i can use those new actions

It would be awesome to have support for Bun and Deno given there is some interest in both of those runtimes and with Bun/Deno we could utilize their native APIs for the server part to max out potential performance of the function handlers.

@sanketsudake something got messed up in my rebasing 😅 so i closed the PR here and re-opened it again #424
