Status](https://github.com/mysticatea/eslint4b/workflows/CI/badge.svg)](https://github.com/mysticatea/eslint4b/actions)\n[![Dependency Status](https://david-dm.org/mysticatea/eslint4b.svg)](https://david-dm.org/mysticatea/eslint4b)\n\nESLint which works in browsers.\n\n## 🏁 Goal\n\nESLint doesn't support browsers officially, but we can use it similar to [the official online demo](https://eslint.org/demo/).\nThis package provides the [Linter] class which is modified to work in browsers.\n\n- Eliminate the dependency to `fs`.\n- Eliminate the dynamic `require()`s.\n\nThis package is kept latest with cron jobs GitHub Actions provide.\n\n## 💿 Installation\n\nUse [npm](https://www.npmjs.com/) to install.\n\n```\nnpm install eslint4b\n```\n\n## 📖 Usage\n\nUse a bundler such as [Webpack]. The `eslint4b` must be able to be bundled.\n\n```js\nconst Linter = require(\"eslint4b\") // import Linter from \"eslint4b\"\nconst linter = new Linter();\n\n// Verify a code.\n// See the official document of the Linter class.\nconst messages = linter.verify(\n    \"var foo = 0\",\n    {\n        rules: {\n            semi: \"error\"\n        }\n    },\n    { filename: \"foo.js\" }\n);\n```\n\nAlso, you can use the [Linter] class which doesn't include any core rules.\nIt's lightweight than the full set.\n\n```js\n// This Linter doesn't include any core rules.\nconst Linter = require(\"eslint4b/dist/linter\")\n\n// You can load core rules individually.\nconst { indent, quotes, semi } = require(\"eslint4b/dist/core-rules\")\nconst linter = new Linter()\nlinter.defineRule(\"indent\", indent)\nlinter.defineRule(\"quotes\", quotes)\nlinter.defineRule(\"semi\", semi)\n```\n\n## 📰 Changelog\n\nSee [GitHub releases](https://github.com/mysticatea/eslint4b/releases).\n\nIf no description, it's the build of ESLint in the same version.\nIt doesn't have any notable change.\n\n## ❤️ Contributing\n\nContributing is welcome.\n\nPlease use GitHub issues/PRs.\n\n### Development tools\n\n- `npm test` runs tests.\n- `npm run build` build ESLint which works in browsers.\n\n[Linter]: https://eslint.org/docs/developer-guide/nodejs-api#linter\n[Webpack]: https://webpack.js.org/\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmysticatea%2Feslint4b","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fmysticatea%2Feslint4b","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmysticatea%2Feslint4b/lists"}
