I can't import testing-library/react in my project - javascript

I am trying to write tests using #testing-library/react in my create-react-app with Typescript, but for some reason the module does not seem to import:
Even my editor complains:
The error reads:
Could not find a declaration file for module '#testing-library/react'. '/home/dbugger/projects/foo/node_modules/#testing-library/react/dist/index.js' implicitly has an 'any' type.
Why is this happening?

Module not found error even when overriding webpack config

When running npm run build I'm getting Module not found error. The extension in the request is mandatory for it to be fully specified.
This is relating to a shared package I created using create-react-library. This lib is being referenced in a new project using the latest create-react-app.
I have created a config-overrides.js file setting fullySpecified to false but this does not seem to have any affect.
Any idea what I am missing?
Module not found: Error: Can't resolve './utils' in
'C:\Users\Bob\source\repos\my-react-app\node_modules#my-lib\shared\dist\services'
Did you mean 'utils.js'? BREAKING CHANGE: The request './utils' failed
to resolve only because it was resolved as fully specified (probably
because the origin is strict EcmaScript Module, e. g. a module with
javascript mimetype, a '.mjs' file, or a '.js' file where the
package.json contains '"type": "module"'). The extension in the
request is mandatory for it to be fully specified. Add the extension
to the request.

Jest is not collecting coverage from all my Vue files

I am testing a Vue3 project with Jest and I am facing this issue: I recently added Jest to my Vue project through the command vue add unit-jest. This command configured the environment to run unit tests with the command npm run test:unit, which refers to vue-cli-service test:unit.
I've also configured Jest in my package.json file with options "collectCoverage":true and "collectCoverageFrom":["src/views/**.{js,vue}","!src/main.js"].
However, when I run the tests, I don't get a coverage report from all of my Vue components, only some of them. These components are located in src/views folder of my project.
This is my package.json file:

Heap Out of Memory in React Application

Heap Out of Memory error while starting the application. I have listed my package.json file content which might be needed for proper detailing. Although I set max_old_space_size to 4096, it still provides me the same error. My Pc configuration is 4GB RAM and I5 intel processor. Is it due to my pc configuration or memory leaks in the code. Please elaborate the possible fix for the issue. I face this issue when I use sass in my dev dependencies.

VSCode EsLint Extension Does Not Lint in JS Files in a Mixed Next.JS Project, but next lint and Husky Work

For context, our project is a Next.JS project with mostly JavaScript files, and a few scattering of random TypeScript Files, mostly in our API folder. Recently we set up Husky to pre-commit our git commits, and some of the settings changed and while next lint correctly lints, and our Husky settings work with both types of files, the VSCode extension for EsLint no longer works on JavaScript files. While removing plugin:#typescript-eslint/recommended fixes that issue, next lint and husky then fails with TS files.

I have found no good resources on addressing this issue for mixed projects like this. I do not know why we have typescript files as they were added before I joined.
This eslint file is missing the typescript parser:
"parser": "#typescript-eslint/parser",
