Guide on accessing js file in an Angular application

I have a component where I need to create a function that can search for a specific string value in the provided JavaScript file. How can I achieve this? The file path is '../../../assets/beacons.js' (relative to my component) and it's named beacons.js

const allBeacons = {
    "RIPE": [
        "84.205.64.0/24",
        "84.205.65.0/24",
        "84.205.67.0/24",

        "84.205.77.0/24",
        "84.205.78.0/24",
        "84.205.79.0/24",
        "84.205.73.0/24",
        "84.205.82.0/24",
        "93.175.149.0/24",
        "93.175.151.0/24",
        "93.175.153.0/24"].map(i => i.toLowerCase()),
    "rfd.rg.net": [
        "45.132.188.0/24",
        "45.132.189.0/24",
        "45.132.190.0/24",
        "45.132.191.0/24",

Answer №1

To ensure the js file is included in the bundle, you must inform Angular about it:

  1. Firstly, navigate to angular.json and insert the path to the "scripts" array:
"scripts": ["src/assets/beacons.js"]
  1. Prior to declaring the component class in your file, make sure to declare the variable as global to prevent TypeScript errors (the variable name should match the one in the js file):
  type Beacons = {/* Define type if necessary */} | any
  declare const allBeacons: Beacons
  1. You can now utilize it as a global variable within your application:
ngOnInit() {
  console.log(allBeacons)
}
