Property 'Unit' does not exist on type 'MathJsStatic'. Did you mean 'unit'? error in Typescript

[HendrikPetertje]

When creating the following code in Typescript

import { MathJsStatic, create, all, MathType } from 'mathjs';
const math: MathJsStatic = create(all, {}) as MathJsStatic;

math.createUnit('cells'); // works perfectly
math.Unit; // results in: Property 'Unit' does not exist on type 'MathJsStatic'. Did you mean 'unit'?

It looks like Unit isn't properly part of the new MathJS typescript definitions or it's not linking correctly.

if I replace the line above with window['testing'] = math then the Unit is in fact present.

Edit: I am running mathjs 9.4.4 without @types/mathjs (relying on the built-in type definitions)

Thanks for reporting!

Anyone able to help out adding type definitions for Unit?

[janniklas-jakob]

As described in this discussion, I cannot retrieve math.Unit.UNITS in typescript.

However, the following code works:

import { all, create } from "mathjs";
const math = create(all);
// @ts-ignore
console.log(math.Unit.UNITS);

Is this still being worked on?

Thanks for reporting Jakob. There is no one working on that right now, help would be welcome.

And indeed, you can resort to @ts-ignore as a workaround.
