Charts Vendor

Vendored dependencies for @mui/x-charts.

An adaptation of the victory-vendor

Background

D3 has released most of its libraries as ESM-only. This means that consumers in Node.js applications can no longer just require() anything with a d3 transitive dependency, including much of @mui/x-charts.

To help provide an easy path to folks still using CommonJS in their Node.js applications that consume @mui/x-charts, we now provide this package to vendor in various d3-related packages.

Main difference with victory-vendor

Victory is using the d3-voronoi which is an archived project.

Packages

We presently provide the following top-level libraries:

• d3-color
• d3-interpolate
• d3-sankey
• d3-scale
• d3-shape
• d3-time
• d3-timer

This is the total list of top and transitive libraries we vendor:

• d3-array
• d3-color
• d3-format
• d3-interpolate
• d3-path
• d3-sankey
• d3-scale
• d3-shape
• d3-time
• d3-time-format
• d3-timer
• internmap

How to add a new package

To add a new package, simply install it as a dependency in this package, and then run the build script.

If your package is not built, you may need to adjust the parameters on ./scripts/build.js, then run the build script again.

How it works

We provide two alternate paths and behaviors -- for ESM and CommonJS

ESM

If you do a Node.js import like:

import { interpolate } from '@mui/x-charts-vendor/d3-interpolate';

under the hood it's going to just re-export and pass you through to node_modules/d3-interpolate, the real ESM library from D3.

CommonJS

If you do a Node.js import like:

const { interpolate } = require('@mui/x-charts-vendor/d3-interpolate');

under the hood, it will go to an alternate path that contains the transpiled version of the underlying d3 library found at x-charts-vendor/lib-vendor/d3-interpolate/**/*.js. This further has internally consistent import references to other x-charts-vendor/lib-vendor/<pkg-name> paths.

Note that for some tooling (like Jest) that doesn't play well with package.json:exports routing to this CommonJS path, we also output a root file in the form of x-charts-vendor/d3-interpolate.js.

Licenses

This project is released under the MIT license, but the vendored in libraries include other licenses (for example ISC) that we enumerate in our package.json:license field.
