leanup js

The @leanup ecosystem stands for a lightweight and pure way for application development in JavaScript/TypeScript.

Motivation

  • Learnability
  • Controllability
  • Universality
  • Flexibility
  • Scalability
  • Durability
  • Transparency

What makes the difference

Stop the transitive knowledge.

We use the minimal configuration and build no overhead stuff on top of the popular tools and make every native command transparent.

Principles

  • convention over configuration
  • pure commands under the hood
  • don't repeat yourself
  • following the generic instead of the influenced way
  • keep the dependencies always up to date

Arguments

The arguments for and against this concept are documented here:

Pro

  • select only one pure and popular tool for each use case (e.g. bundling, unit-test)
  • there are extensible configuration files for each tool
  • due to the flat dependencies we can always stay up to date
  • the CLI bundles all the necessary tools in a portable/scalable way
  • the risk to get vulnerabilites in dependencies is lower
  • leanup's own code is kept to a minimum

Contra

  • please give feedback
  • please show us your perspective

TSArch Architecture in progress hint
Webhint Webhint ✔️ moved *** hint
TestCafe E2E-Test-Runner will be evaluated **** testcafe
TSLint Code-Checker removed ** tslint
Cypress E2E-Test-Runner excluded * cypress

* Arguments agains Cypress:

  • reinvent wheel
    • detect css selectors
    • BDD test syntax
    • principals
  • large tooling
  • a lot of binaries
  • many dependencies
  • ci integration vs selenium hub

It is difficult to keep focus with Cypress as it is more a nice tool than an effective tool. It is expected that a lot of time will be invested to justify the requirements of a project.

** TSLint is deprecated.

*** Webhint is not practical for the development of components, since component tags often have no relation to standard HTML. In addition, the webhint package alone is over 100 MB in size. I have good by using a IDE webhint plugin, like VSCode webhint.

**** TestCafe The idea that defined TestCafe architecture was that you don't really need an external driver to run end-to-end tests in the browser. That's interesting.
