Error when running jest with components that import this package

[devTeaa]

Hi, I've problems when jest trying to run unit test that uses this package, I've read that we need to manually transpile this? But I'm not using typescript, is there an example for me to use? My stack isn't on vue-cli so I have my own webpack/loader etc. Also it would be nice if the default is transpiled instead of us figuring out how to transpile this ourselves for our project.

PS. I have added transformIgnorePatterns on jest.config.js, after that I'm a bit lost

You can use the files at "vue-composition-helpers/dist"

It have the same functions, but compiled.

The fact you can compile yourself can help you to tree-shake only the things you use, and the ability to work with vue-cli, vite, nuxt build, as native es-modules, or customized webpack config.

I did import from vuex-composition-helpers/dist but it still shows some transpiling error like "$export is not a function" from jest

I resolved it by put

transformIgnorePatterns: [
    "/node_modules/(?!vuex-composition-helpers).+\\.js$",
  ],

into jest.config.js
