NodeJs

Setup

Running start up scripts in node

"scripts": {
  "start": "run-p start:dev start:api",
  "start:dev: "webpack-dev-server --config webpack.config.dev.js --port 3000",
  "prestart:api": "node tools/createMockDb.js",
   "start:api": "node tools/apiServer.js"
};

The run-p runs multiple jobs, pre<value> runs the command before the value without pre

Adding consts in webpack

To pass dev/production consts we can do this using webpack. Include webpack in you webpack.config.dev.js and webpack.DefinePlugin e.g.

const webpack = require("webpack")
...
plugins: [
    new webpack.DefinePlugin({
        "process.env.API_URL": JSON.stringify("http:://localhost:3001")
    })
],
...
