 7 | [![Deploy](https://www.herokucdn.com/deploy/button.png)](https://heroku.com/deploy?template=https://github.com/heroku-examples/node-workers-example)
 8 | 
 9 | ## Installing Local Dependencies
10 | 
11 | - [Redis](https://redis.io/)
12 | 
13 | ```
14 | $ brew install redis
15 | $ brew services start redis
16 | ```
17 | 
18 | ## Getting Started
19 | 
20 | 1. `npm install`
21 | 2. `npm start`
22 | 3. [http://localhost:5000](http://localhost:5000)
23 | 
24 | ## Deploying
25 | 
26 | ```
27 | $ git clone git@github.com:heroku-examples/node-workers-example.git
28 | $ cd node-workers-example
29 | 
30 | $ heroku create
31 | $ heroku addons:create heroku-redis
32 | $ git push heroku main
33 | $ heroku ps:scale worker=1
34 | $ heroku open
35 | ```
36 | 
37 | ## Application Overview
38 | 
39 | The application is comprised of two process: 
40 | 
41 | - **`web`** - An [Express](https://expressjs.com/) server that serves the frontend assets, accepts new background jobs, and reports on the status us existing jobs
42 | - **`worker`** - A small node process that listens for and executes incoming jobs
43 | 
44 | Because these are separate processes, they can be scaled independently based on specific application needs. Read the [Process Model](https://devcenter.heroku.com/articles/process-model) article for a more in-depth understanding of Heroku’s process model.
45 | 
46 | The `web` process serves the `index.html` and `client.js` files which implement a simplified example of a frontend interface that kicks off new jobs and checks in on them.
