w3i

w3i

A typescript library for handling configuration for modules imported by other modules.

This package offers opinionated methods implemented in packages that have configurations.

With this module other packages can easily expose a .set method for setting their parameters.

Implementation

A common implementation is the following:

• Import and instanciate the Weights class:

// src/config/index.ts
import {Weights, DeepPartial} from 'w3i';

type Config = {
  debug: boolean
}

export const weights = new Weights<Config>({
  debug: false,
});

export const set = (params: DeepPartial<Config>) => {
  weights.set(params);
};

• Export a set method in order to set the configuration:

// src/main.ts
import {set} from './config/index.js';
export const config = {set};

• Use the configuration inside the package:

// src/business.ts
import {weights} from './config/index.js';

function main(){
  if(weights.params.debug === true){
    console.log('Debugging...');
  }
}
