Usage

1. Create a functions folder:

   mkdir functions

2. Create a function file (e.g., example.js):

   const bfast = require('bfast');
   
   exports.myHttpFunction = bfast.functions().onHttpRequest('/hello', (request, response) => {
       response.status(200).send('Hello, World!');
   });
   
   exports.mySocketFunction = bfast.functions().onSocketIO('echo', (request, response) => {
       response.emit('echo', request.body);
   });

3. Start the BFast Function engine:

   Create an index.mjs file in your root workspace and start the Faas server:

   import {start} from 'bfast-function';
   
   start({
       port: '3000',
       functionsConfig: {
           functionsDirPath: './functions',
       }
   }).catch(console.log);

   Then, start the server:

   node index.mjs

Docker

You can also run the BFast Function engine in a Docker container.

1. Build the Docker image:

docker build -t bfast-function .

2. Run the Docker container:

docker run -p 3000:3000 bfast-function

This will start the BFast Function engine and expose it on port 3000.

You can also mount a local functions folder to the container:

docker run -p 3000:3000 -v $(pwd)/functions:/app/functions bfast-function

This will mount the functions folder in your current working directory to the /app/functions folder in the container.
