• bfast functions

john@pc:~/Desktop/my-workspace$ npm install bfastfunction --save

• bfast client

john@pc:~/Desktop/my-workspace$ npm install bfast --save

2. Create a functions folder

Create any folder in your working space

john@pc:~/Desktop/my-workspace$ mkdir functions

3. Create a functions file ( e.g example.js )

Create a file of any name in functions folder you already create from step 2 and past the following code

const bfast = require('bfast');

module.exports.myHelloFunction = bfast.functions().onHttpRequest('/hello', (request, response)=>{
    response.status(200).send('Hello, World!');
});

4. Start BfastFunctions engine

create index.mjs file in your root workspace and start the Faas server like the following

const {start} = require('bfastfunction');
start({
    port: '3000',
    functionsConfig: {
        functionsDirPath: './functions',
    }
}).catch(console.log);

then to start listening run ~$ node index.mjs
