Error - Module '"jsep"' has no exported member 'Jsep'

[HimanshuGoel]

I am getting an error Module '"jsep"' has no exported member 'Jsep' while importing the Jsep library by using the below statement -

import { Jsep } from 'jsep';

I am using the 1.3.8 version of Jsep library in a standard Angular 15 application.

However, it works fine when I use the default import syntax -

import jsep from 'jsep';

I have also created a minimal reproduction example on Github. Please refer to this link to open it on Stackblitz - https://stackblitz.com/github/HimanshuGoel/issues-reproduction-app/tree/jsep-issue-with-import?file=src%2Fapp%2Fapp.component.ts

Looks like Jsep isn't included in TypeScript, but both of these work:

import * as jsep from 'jsep'
const { Jsep } = jsep
console.log(Jsep.parse('1 + 1'))

import { Jsep } from 'jsep'
console.log(Jsep.parse('1 + 1'))

If you look at the git log, it looks like the types are manually built: https://github.com/EricSmekens/jsep/commits/master/typings/tsd.d.ts

#198 proposed some updates to the typings, but the review comments indicate that it broke some of the other usages of jsep with cjs and esm. Would be great if someone wanted to create a PR?

I suggest just using the jsep() API.

I don't have a use case for being able to use Jsep.parse in TypeScript the but I might have a use case for #211. I don't know yet. I think a fix for #211 could make this one easier.

@benatkin

import * as jsep from 'jsep'
const { Jsep } = jsep
console.log(Jsep.parse('1 + 1'))

This works in runtime in browser, but its failing in Jasmine unit test.
Jsep comes undefined in jasmine unit test Angular i.e. * export only default not Jsep during tests execution.
