ts-api-utils and tslib dependencies should be used or removed about node-typescript-boilerplate

[kmturley]

Thanks for your prompt response. I understand what the libraries are, i'm questioning the need for them.

https://www.npmjs.com/package/tslib and importHelpers configuration reduces code size when compiling to es2015, but your project uses es2022.

For example:

git clone https://github.com/jsynowiec/node-typescript-boilerplate.git
cd node-typescript-boilerplate
npm install
npm run build
cat ./build/src/main.js

Then update tsconfig.json value"importHelpers": false and then:

npm run build
cat ./build/src/main.js

Notice nothing has changed in the built main.js file.

Then update tsconfig.json valueES2015 and then:

npm run build
cat ./build/src/main.js

Notice the bloat code is there for es2015, so tslib is useful for es2015.

I didn't try every helper method in: https://github.com/microsoft/tslib/blob/main/modules/index.js
but my assumption is many of these are not needed when compiling to es2022

I appreciate your comment. Because this project has been around for 8 years now, and went through many updates and switched over several Node and TypeScript LTS versions and ES targets, this indeed may be an obsolete artifact now. I will take a look at some point if it is fine to remove, and it does not break anything.

However, I am still convinced that ts-api-utils needs to stay pinned. It is used by, for example, eslint. In the past, there were at least a few non-obvious problems related to version incompatibilities with the old tsutils, what ts-api-util replaces, and the linter and its dependencies.

This has already been discussed.

tslib is a runtime library for TypeScript importHelpers. When this compiler option is enabled, you need to ensure that the tslib module is available at runtime.
