node-compose

Start node-processes as with docker-compose and with a neat little ui.

Detailed npm trends and stats

Important

node-compose is for development only! Don't use it in production!

Prerequisite

node-compose needs nodemon to be installed globally.

Install nodemon: npm install -g nodemon

Install

npm install -g node-compose

Example

Try a simple example repo or create your own example with following steps.

1. Create multiple servers. (eg for multiple microservices)

   ./process-a/index.js (Port 3000)

   const http = require('http');
    
   const hostname = '127.0.0.1';
   const port = 3000;
    
   const server = http.createServer((req, res) => {
     res.statusCode = 200;
     res.setHeader('Content-Type', 'text/plain');
     res.end('Hello World\n');
   });
    
   server.listen(port, hostname, () => {
     console.log(`Server running at http://${hostname}:${port}/`);
   });

   ./process-b/index.js (Port 4000)

   const http = require('http');
    
   const hostname = '127.0.0.1';
   const port = 4000;
    
   const server = http.createServer((req, res) => {
     res.statusCode = 200;
     res.setHeader('Content-Type', 'text/plain');
     res.end('Hello World\n');
   });
    
   server.listen(port, hostname, () => {
     console.log(`Server running at http://${hostname}:${port}/`);
   });

2. Create a compose-file. node-compose.yml

   process_a:
     build: ./process-a
     environment:
       - NODE_ENV=development
    
   process_b:
     build: ./process-b
     environment:
       - NODE_ENV=development

3. Start node-compose shell with node-compose. Inside the shell start all processes with start all or type help for more information about possible commands.

Commands

Commands:
    help [command...]            Provides help for a given command.
    exit                         Closing shell and stop all images
    ps                           List running images
    reload                       Reloads config file and restarts processes if needed.
    start <image> [images...]    Start an image by <name> or all
    stop <image> [images...]     Stop an image by <name> or all
    restart <image> [images...]  Restart one or more images by given name or all
    images                       List all images found in config file.
    monitor [options]            Start web monitor
    start-script <image:script>  Start a script of an image
    stop-script <image:script>   Stop a script of an image
 

Todo

• Use nodemon as a module to avoid global dep.
• Add more information about running processes to ps-view.

Tests

Tests are written with mocha.

1. Clone repo git clone https://github.com/platdesign/node-compose.git
2. Move to repo directory. cd node-compose
3. Install all dependencies. npm install
4. Run tests with mocha
