Creating a versatile JavaScript/TypeScript library

My passion lies in creating small, user-friendly TypeScript libraries that can be easily shared among my projects and with the open-source community at large. However, one major obstacle stands in my way:

Time and time again, I run into issues where an NPM module I've developed works perfectly in one environment but encounters strange errors in others. It might function flawlessly in create-react-app, for example, but fail miserably in ts-node. Or it could behave well everywhere except for during the build process, despite being a pure function devoid of context-dependent elements like 'window'.

How can I avoid encountering these frustrating problems?

Is there some sort of "magic" solution that would allow me to test my creations in every conceivable scenario and combination - from browsers to old browsers lacking ES6 support, typescript projects to create-react-app projects, node environments to ts-node instances, ES modules to those imported via require or import statements...?

I yearn for a simple and unified approach to writing code, without having to spend excessive amounts of time configuring and updating (TS, webpack) setups or drowning in boilerplate code.

Imagine having a library that automatically builds for all platforms and inserts the configurations into package.json effortlessly – essentially, a "create-react-app" equivalent tailored specifically for libraries.

Answer №1

Thank you for your dedication to the open-source community!

While working on my latest project, I encountered a similar issue that got me thinking. I decided to take a shortcut and limit the scope by coding the library in JavaScript instead of TypeScript. However, there are some drawbacks to this approach:

  • JavaScript can remain uncompiled, allowing clients to handle compilation themselves when using ES modules.
  • In contrast, TypeScript modules published on npm require compilation, leading to additional setup and infrastructure for building and publishing code.

If you're interested in collaborating on this particular use case, let's connect. It might be beneficial to explore creating a code generator tailored specifically for libraries, akin to what I discussed in How to quickly start a webpack project. Having someone to brainstorm ideas with could streamline the process, especially given the complexities of webpack configurations.
