FionnT / Outage-Dashboard

An outage management, communication tool originally built for the Customer Service teams at Netflix.

node-react-app

The front-end file structure and build configuration is based on the create-react-app boilerplate, see the create-react-app README for details on customization.

Getting started

Setting up your development environment

Make sure that you've installed Node.js

Developing your app

Update configurations in the following files:

$ ./server/helpers/slack-bot/index.js
$ ./server/helpers/db-connect.js
$ ./server/helpers/send-alert-email.js
$ ./src/data/[all files and folders]

Start a local dev server by running the following command:

$ yarn start

This will open localhost:3000 in your browser and begin serving your app with live-reloading enabled.

Features

Webpack config and build system

Has the batteries-included modern JS build system from create-react-app with a few extra defaults:

• A production build is placed in the built/ directory to avoid name conflicts with other internal tools
• Chunk inlining is disabled to adhere to a stricter content security policy.
• Uses a local .eslintrc file for linting rules if one exists.

create-react-app file structure

public/ contains your root index.html.

src/ is the primary front-end working directory and contains a few basic React components and stylesheets to get you started (the Express server is in src/).

Default Express configuration

The server serves the files in built/ statically by default, and disables client-side caching. If it doesn't recognize a path, it will serve up index.html so that client-side routing works.

The server listens on localhost only by default, with the expectation that you'll use Apache as a proxy. If you want to access the app directly on port 7101, remove the "localhost" argument from app.listen() in server/index.js.

nodemon

The start command will run the server through nodemon so that it automatically restarts when you make changes during local development.

Modifying the eslint rules

By default, this app uses eslint-config-react-app for its linting rules. If you're getting warnings you don't want (or aren't getting warnings you do want), you can override that default configuration with the .eslintrc file in the project root:

{
    "extends": "react-app",
    "rules": {
        // your customizations here
    }
}

npm vs. yarn

The default commands use yarn instead of npm to run scripts, and the repo includes a starting yarn.lock file. You shouldn't see a difference from using yarn vs. npm, but beware that using npm instead of yarn, or mixing a package-lock.json and a yarn.lock file together could result in unpredictable versions of your dependencies.
