Why #

Make your project structure pretty by linting it 🗂

Directory structure rules are an important part of any project. These rules help to raise clarity of the project and reduce its complexity. Having a clearly defined structure make developers always know where to put files and where to find them. If the project is big enough, it is necessary to avoid chaos in it.

folderslint let you configure directory structure rules and check if existed or new files fit these rules.

Quick Overview #

Install folderslint globally:

pub global activate folderslint

or install it as a dev dependency

pub add dev:folderslint 

Setup a config file .folderslintrc in the root of the project.

Run folderslint to check the whole project or a directory (i.e. /components):

(if installed globally)

folderslint components

if installed as a dev dependency

dart run folderslint components

Configuration #

folderslint needs configuration file named .folderslintrc in the root of the project.

The example of the config:

{
  "root": "src", // optional
  "rules": [
    "components/*",
    "pages/components/*/utils",
    "hooks",
    "legacy/**"
   ]
}

root is the directory the structure of which should be checked.

rules is an array of rules which define permitted directory paths.

Root directory #

You have to specify root if you want to check structure in a specific directory. Directories which are out of the root will not be checked. If you want all the directories of the project to be checked, you don't need to specify root.

Rules syntax #

There are 3 ways to specify a rule:

  • the exact path of a directory,
  • * instead of a directory name if any directory accepted on that level,
  • ** at the end of a rule instead of a directory name if any directory accepted on any lower level.

⚠️ ** can be used only at the end of a rule because it doesn't make sense to use it at the middle of a rule. It would make any number of nested directories in the middle of a path accepted which gives too much flexibility for the idea of clearly defined directory structure rules.

For example:

Rule Meaning
hooks ✅  The directory hooks (and files in it) is accepted.
❌  Any nested directory is not accepted.
components/* ✅  The directory components is accepted.
✅  Any first level nested directory is accepted.
❌  Any second level nested directory is not accepted.
components/*/utils ✅  The directory components is accepted.
✅  Any first level nested directory is accepted.
✅  The second level nested directory utils is accepted.
❌  Any other second level nested directory is not accepted.
legacy/** ✅  The directory legacy is accepted.
✅  Any nested directory on any level is accepted.
components/*/legacy/** ✅  The directory components is accepted.
✅  Any first level nested directory is accepted.
✅  The second level nested directory legacy is accepted.
❌  Any other second level nested directory is not accepted.
✅  Any nested directory on any level inside of legacy directory is accepted.

⚠️ A rule like components/*/utils automatically make the components and components/* rules work. So, no need to specify a rule for every level directory. You need to specify the deepest path.

⚠️ It's not recommended to overuse ** pattern. It lets absence of structure to sprout in your project. Still it could be useful for some directories which have messy structure by its nature - i.e. node_modules, not maintained legacy directories.
