Description

Nammatham (นามธรรม in Thai, pronounced /naam ma tham/, means abstract in Thai) is Azure Function Nodejs.

Getting Started for Azure Functions

Install

# Including all packages
npm install nammatham@alpha

Example

You can see examples or follow the minimal app getting started below:

initNammatham.create() is a factory function for creating Nammatham App, it's a wrapper for Azure Functions App.

import { initNammatham, expressPlugin } from 'nammatham';

const n = initNammatham.create();
const func = n.func;
const app = n.app;

const helloFunction = func
  .httpGet('hello', {
    route: 'hello-world',
  })
  .handler(async c => {
    c.context.log('HTTP trigger function processed a request.');
    c.context.debug(`Http function processed request for url "${c.trigger.url}"`);
    const name = c.trigger.query.get('name') || (await c.trigger.text()) || 'world';
    return c.text(`Hello, ${name}!`);
  });

app.addFunctions(helloFunction);

const dev = process.env.NODE_ENV === 'development';
app.register(expressPlugin({ dev }));
app.start();

Then edit package.json like this;

{
  "main": "dist/src/main.js",
  "scripts": {
    "dev": "cross-env NODE_ENV=development tsx watch src/main.ts",
    "start": "tsc && func start"
  }
}

Run Dev Server on locally, (For dev server use tsx watch for reloading run dev server using express )

npm run dev

Run Azure Functions on locally (Using Official Azure Functions Node.js)

npm start

Nammatham Packages

• core, Nammatham Core package for initializing Nammatham App

Available Adatpers

• azure-functions, Azure Functions Adapter for Nammatham, internally, Azure Functions in local dev mode is dependend on Express.js.

Available Plugins

• express, Express Plugin for run server. Nammatham itself doesn't contain any server, enabling this plugin to provide better DX than the original server e.g. Azure Functions Runtime
• trpc-azure-functions, provide tRPC Plugin for Azure Functions, inclduing express server for local testing.

Local Dev Setup

# Install dependencies
pnpm install
# Before dev (Update workspace to local dependencies)
pnpm pre-local && pnpm install
# While dev
pnpm dev
# After dev before submitting PRs (Update workspace to actual dependencies), `pnpm install` for making sure lockfile is correct.
pnpm post-local && pnpm install
# Release package
pnpm release
