library3.0.1jsnpmunverified

An ESLint plugin that lints Eta v3 template files. Version 3.0.1 is current and stable, with a low release cadence. It processes .eta files through a custom processor, enabling ESLint rules on Eta templates. Key differentiators: built specifically for Eta v3, supports JavaScript-like syntax inside templates, and integrates seamlessly with standard ESLint workflows. Alternatives like eslint-plugin-eta target older Eta versions. Requires ESLint >=8 and eta >=3 as peer dependencies.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

plugin (as object)
✓ const eta3Plugin = require('eslint-plugin-eta-3');
✗ import { eta3Plugin } from 'eslint-plugin-eta-3';
CommonJS require is idiomatic; there is no named export for the plugin object.
Processor
✓ // Not directly exported; use 'eta-3/eta' in ESLint config
✗ import { EtaProcessor } from 'eslint-plugin-eta-3';
The processor is referenced as a string path in ESLint config, not imported.
Plugin name
✓ plugins: ["eta-3"]
✗ plugins: ["eslint-plugin-eta-3"]
ESLint expects the short name without the 'eslint-plugin-' prefix.

Shows installation, plugin and processor configuration for ESLint, and an example template to lint.

// Install npm install --save-dev eslint eslint-plugin-eta-3 eta@^3 // .eslintrc.js module.exports = { root: true, env: { browser: true, es2021: true }, plugins: ["eta-3"], overrides: [ { files: ["*.eta"], processor: "eta-3/eta", rules: { // Example rules "no-unused-vars": "error", "no-undef": "error" } } ] }; // Example Eta template: template.eta // <% let name = "World" %> // <h1>Hello <%= name %></h1> // Run linter npx eslint template.eta
