flay - filesystem layout linter

Usage:

In the root of your JavaScript project:

  yarn add -D git://github.com/mzedeler/flay
  yarn flay .

This will then lint your filesystem according to the following rules:

Compound directories must contain an index file

Ok:

  MyFancyComponent
    +-- index.ts
    +-- MyFancyComponent.tsx
    +-- MyFancyComponent.test.tsx

Not ok:

  MyFancyComponent
    +-- MyFancyComponent.tsx
    +-- MyFancyComponent.test.tsx

Collection directories must not contain an index file

Ok:

  components
    +-- MyFancyComponent.tsx
    +-- MyOtherFancyComponent.tsx

Not qk:

  components
    +-- index.ts
    +-- MyFancyComponent.tsx
    +-- MyOtherFancyComponent.tsx

Definitions

Currently, compound directories are defined as any directory with a capital letter in the name.

Any non-compound directory is classified as a collection.

Ignore file

It is possible to skip validation of a directory by adding it to .flayignore, but this only works if you add the exact path of every directory you want to ignore:

To ignore foo/bar here:

  foo
    +-- bar

Put foo/bar in a top level .flayignore file or but bar in a .flayignore file in foo.
