eslint-plugin-fest

0.2.4 verified Fri May 01 auth: no javascript deprecated

ESLint plugin for linting inline scripts and params in Fest XML template files. Current version 0.2.4 (last updated 2017). Low release cadence, no recent updates. Focuses on enforcing coding standards within Fest templates, similar to how eslint-plugin-html works for HTML files. Differentiator: dedicated to Fest framework.

Common errors

error Error: Failed to load plugin 'eslint-plugin-fest' declared in '.eslintrc.json': Cannot find module 'eslint-plugin-fest' ↓

cause Plugin not installed correctly.

fix

Run npm install --save-dev eslint-plugin-fest

Warnings

gotcha Plugin requires ESLint to lint .xml files explicitly; without --ext .xml, Fest files are ignored. ↓

fix Use eslint --ext .xml,.js src or configure eslint.extensions in your editor.

deprecated The package has not been updated since 2017 and is likely unmaintained. ↓

fix Consider alternatives like eslint-plugin-html for generic template linting.

Install

Imports

wrong
```
plugins: ['fest']

correct

plugins: ['eslint-plugin-fest']
```
ESLint requires the full 'eslint-plugin-' prefix or the shorthand 'fest', but the example in README uses 'eslint-plugin-fest'.

Quickstart

Adds the fest plugin to ESLint and enables a rule. Lint Fest XML files with the --ext flag.

// .eslintrc.json
{
  "plugins": ["eslint-plugin-fest"],
  "rules": {
    "fest/rule-name": "error"
  }
}
// Lint command: eslint --ext .xml,.js src
