Example

Create file example.js

#!/usr/bin/env node

const {forExpress, addUser} = require("modulino");
const express = require('express');
const bodyParser = require('body-parser');
const expressWs = require('express-ws');

const app = express();
expressWs(app);

// support json encoded bodies
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({extended: true}));

const port = 8000;

addUser({
  "username":"test",
  "name":"User",
  "emails":["test@test.com"],

);

forExpress(app, {
    consoleLogger: true,
    contexts: [
        {path: 'web', headers: {host: `localhost:${port}`}}
    ],
    administrationApi: '/administrationApi',
}).then(() => app.listen(port, () =>
    console.log(`server started on port http://localhost:${port}`)
));

Run this commands

npm install --save modulino body-parser express express-ws

node example.js

Create file web/test.mod.js

const {onRequest} = require('api');

onRequest((req, res) => {
    const {body} = req;
    res.type('js');
    res.send({message:"Hello world!", requstData: body});
});

Open the test service.

You can edit file web/test.mod.js without any server restarts and check that your service is changing results.

Create file web/index.html

<!DOCTYPE html>
<head>
    <title>Title</title>
</head>
<body>
 Hello
</body>
</html>

Open the main page.

Notice: This module has 'nodemailer' NPM dependency.

Run this commands to be able to remotely

npm install modulino ws

node client.js

It will download all files from server and upload them after any change on filesystem. It also shows logs from server.

Get public key in PEM format from your ssh RSA key pair:

ssh-keygen -f ~/.ssh/id_rsa -e -m pem

Generating your own keys using NodeJS (newest version required):

const { generateKeyPair } = require('crypto');

generateKeyPair('rsa', {
    modulusLength: 2048,
    publicKeyEncoding: {type: 'pkcs1', format: 'pem'},
    privateKeyEncoding: {type: 'pkcs1', format: 'pem'}
}, (err, publicKey, privateKey) => {
    if (!err) {
        console.log(
            'RSA key generated, you can add user on server: \n\n'+

            'addUser('+JSON.stringify({
                username: "test",
                name: "User",
                emails: ["test@test.com"],
                sshKeys: [{name: "test", publicKey}]
            })+');\n\n\n' +

    }
