A more efficient method for importing numerous 'export' statements using ES6 or TypeScript

Currently, I am utilizing D3.js V4 with the module and my goal is to import multiple modules into a singular namespace. The code snippet provided below showcases my current approach, but I am curious if there is a more efficient method available.

const d3 = Object.assign(
  {},
  require('d3-axis'),
  require('d3-selection'),
  require('d3-format')
)

Whenever I require something, I simply use it as shown below:

d3.format('.5s')
// OR
d3.select(something)

I am wondering if there exists a cleaner way to consolidate all imports under a single d3 namespace?

Answer №1

Utilizing multiple 'export' statements in ES6 or TypeScript

An approach focusing on type safety 

import * as d3Axis from 'd3-axis';
import * as d3Selection from 'd3-selection';

export const d3 = {...d3Axis, ...d3Selection};

Despite this, it is worth noting that the d3 library was developed before TypeScript and lacks support for type safety in its API design choices.

Further Details

Ensuring type safety in your code architecture is crucial, especially when dealing with situations where direct array access may pose a risk. Read more about index signatures in TypeScript here: https://basarat.gitbooks.io/typescript/docs/types/index-signatures.html
