Looking for the most effective method of defining multiple configurations in a multi-build Vue js application?

I am currently developing a Vue 3 web application that is intended to be deployed for various customers, each with their own unique title, logo, and icon.
My goal is to customize the app for each customer by displaying their specific information in the TheFooter.vue component.
An essential requirement is ensuring that when the app is built for a particular customer, no other customers' data should be present in the final built files within the /dist folder after running npm run build, due to privacy concerns.

Here are some approaches I have attempted:

Creating a file named customers.js to export an object structured as follows:

const customers = {
  CUSTOMER_A: {
    title: 'Customer A',
    logo: 'assets/customer_a_logo.png',
    // additional sensitive data
  },
  CUSTOMER_B: {
    title: 'Customer B',
    logo: 'assets/customer_b_logo.png',
    // additional sensitive data
  }
export default const customer[process.env.VUE_APP_CURRENT_CUSTOMER]

Then, defining a key VUE_APP_CURRENT_CUSTOMER in the .env file with values such as CUSTOMER_A, CUSTOMER_B,...
And importing customer data into TheFooter.vue as follows:

const customer = require('./customers.js').default

However, upon inspection of the final built JavaScript files in the /dist directory, it was observed that other customers' information remained accessible.

Utilizing Vue CLI modes, creating individual .env.customer_x files for each customer containing specific data, then referencing the current customer during the build process using the --mode flag (e.g.
```
vue-cli-service build --mode customer_x
```
). However, managing numerous .env.customer_... files may become impractical. (Are there any potential drawbacks to this approach?)
Using a json file (e.g. customers.json) and attempting to import it in TheFooter.vue like so:
```
import { process.env.VUE_APP_CURRENT_CUSTOMER } from './customers.json'
```
It appears impossible to include variables in the import statement, necessitating the use of environment variables (for CI/CD pipelines)

Do you have any suggestions or best practices for addressing this challenge?

Thank you in advance!

Answer №1

To create multiple builds, you can follow a two-step process.

Step 1: Custom script build

Start by writing a custom build script that will trigger Webpack programmatically. Here's an example:

// build.js file
const webpack = require('webpack');

// Your webpack.config.js should export a function instead of config.
const webpackConfig = require('./webpack.config.js');

// You can get data from a separate 'customers.js' file.
const customers = [
  { title: 'App 1' },
  { title: 'App2' }
];

customers.forEach((customer) => {

  // Get webpack configuration for this customer.
  const config = webpackConfig(customer);

  // Invoke the webpack
  webpack(config, (err) => {
    /** Handle error here */
  });

});

Your Webpack config should be wrapped in a callback function like this:

// webpack.config.js
module.exports = (customer) => {

  // This function will be called from the build.js file.
  
  return {
    entry: 'index.js',
    output: { 
      // ...
    }
    // ...other webpack configuration
  };
};

Step 2: Data injection

Inject data into your JavaScript code using Webpack's DefinePlugin or similar methods. For HTML pages, utilize webpack-html-plugin with templates to set metadata such as <title> for each customer's build.

new webpack.DefinePlugin({
  CUSTOMER_DATA: JSON.stringify(customer)
});

Optimize your build script to handle async operations and ensure correct output directory settings for each customer. Additionally, consider utilizing Webpack's array configuration feature for creating multiple builds in a more modular approach.

Remember not to import the 'customers.js' file directly into your code. It should only be used during build time scripts.
