## Motivation

- Learnability
- Controllability
- Universality
- Flexibility
- Scalability
- Durability
- Transparency

## What makes the difference

> <cite>Stop the transitive knowledge.</cite>

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

## Demo's

There are some working examples:

> \*
> 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](https://marketplace.visualstudio.com/items?itemName=webhint.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.
