# noctcore ESLint plugins

> 11 focused ESLint plugins and one lint-meta rule catalog, 113 rules in all, for architecture and correctness conventions generic linters cannot see. Every preset severity is error or off; there are no warnings.

Rule ids are `noctcore-<plugin>/<rule>`. Every rule has one page with its options and Incorrect and Correct examples that run in that package's test suite. The rule docs are the source of truth; nothing on the site restates them.

## Rules

- [All rules](https://noctcore.github.io/eslint-plugins/rules/): one row per rule with the id, what it reports, preset severity and whether it needs type information
- [rules.json](https://noctcore.github.io/eslint-plugins/rules.json): the same index as JSON, one entry per rule with its docs URL, package, preset severity, fixability, type-information needs and deprecation (`deprecated`, `replacedBy`)

## Guides

- [Getting started](https://noctcore.github.io/eslint-plugins/getting-started/): install a plugin, enable its preset, configure the rules that need to know your project
- [Adopting in an existing codebase](https://noctcore.github.io/eslint-plugins/adopting/): enable the preset, switch flooding rules off, re-enable them per directory, never warn
