一旦`eslint-config-ivweb`安装成功，你可以通过[ESLint配置文件]((http://eslint.org/docs/user-guide/configuring)) 中的字段extends中使用它 21 | 22 | ```js 23 | { 24 | "extends": "ivweb", 25 | "rules": { 26 | // Additional, per-project rules... 27 | } 28 | } 29 | ``` 30 | 31 | ### 配合`eslint:recommended`使用`ivweb` 32 | 有部分[eslint:recommended](http://eslint.org/docs/rules/)提到的规则在ivweb中没有提到，因此最好配合eslint:recommend一起使用。 33 | 34 | 只需要同时继承eslint:recommend 和 ivweb 即可，确保 ivweb 放置在最后。部分eslint:recommend定义的规则有点严格，ivweb里面有做定制化的修改。 35 | 36 | ```js 37 | { 38 | "extends": ["eslint:recommended", "plugin:react/recommended", "ivweb"], 39 | "rules": { 40 | // Additional, per-project rules... 41 | } 42 | } 43 | ``` 44 | 45 | ## 如何贡献 46 | 47 | 1. 从目前已经存在的issue或者提出一个新的issue去讨论新的特性或者存在的bug. 48 | 2. 在Github上Fork

Introduction: [eslint-standard.md](docs/eslint-standard.md) 18 | * Rules explanation: [RULES.md](docs/RULE.md) 19 | 20 | ## Usage 21 | 22 | Once the `eslint-config-ivweb` package is installed, you can use it by specifying `ivweb` in the [`extends`](http://eslint.org/docs/user-guide/configuring#extending-configuration-files) section of your [ESLint configuration](http://eslint.org/docs/user-guide/configuring). 23 | 24 | ```js 25 | { 26 | "extends": "ivweb", 27 | "rules": { 28 | // Additional, per-project rules... 29 | } 30 | } 31 | ``` 32 | 33 | ### Using the `ivweb` config with `eslint:recommended` 34 | 35 | There are several rules in the [`eslint:recommended` ruleset](http://eslint.org/docs/rules/) that IVWEB style is not opinionated about that you might want to enforce in your project. 36 | 37 | To use IVWEB style in conjunction with ESLint's recommended rule set, extend them both, making sure to list `ivweb` last: 38 | 39 | ```js 40 | { 41 | "extends": ["eslint:recommended", "plugin:react/recommended", "ivweb"], 42 | "rules": { 43 | // Additional, per-project rules... 44 | } 45 | } 46 | ``` 47 | 48 | To see how the `ivweb` config compares with `eslint:recommended`, refer to the [source code of `index.js`](https://github.com/iv-web/eslint-config-ivweb/blob/master/index.js), which lists every ESLint rule along with whether (and how) it is enforced by the `ivweb` config. 49 | 50 | ## Contributing 51 | 52 | 1. Check for open issues or open a fresh issue to start a discussion around a feature idea or a bug. 53 | 2. Fork [the repository](https://github.com/iv-web/eslint-config-ivweb)_ on GitHub to start making your changes to the **master** branch (or branch off of it). 54 | 3. Write a test which shows that the bug was fixed or that the feature works as expected. 55 | 4. Send a pull request and bug the maintainer until it gets merged and published. :) Make sure to add yourself to [AUTHORS_](AUTHORS). 56 | 57 | ## License 58 | 59 | Apache-2 © IVWEB 60 | -------------------------------------------------------------------------------- /CHANGELOG.md: -------------------------------------------------------------------------------- 1 | 2 | ## [0.1.5](https://github.com/iv-web/eslint-config-ivweb/compare/v0.1.4...v0.1.5) (2018-11-13) 3 | 4 | 5 | ### Bug Fixes 6 | 7 | * 函数名前面不需要加上空格 ([88ac283](https://github.com/iv-web/eslint-config-ivweb/commit/88ac283)), closes [#5](https://github.com/iv-web/eslint-config-ivweb/issues/5) 8 | 9 | 10 | 11 | 12 | ## [0.1.4](https://github.com/iv-web/eslint-config-ivweb/compare/v0.1.3...v0.1.4) (2018-07-18) 13 | 14 | 15 | 16 | 17 | ## [0.1.3](https://github.com/iv-web/eslint-config-ivweb/compare/v0.1.2...v0.1.3) (2018-07-18) 18 | 19 | 20 | ### Bug Fixes 21 | 22 | * eslint-plugin-react dependices.

52 | ``` 53 | 54 | 有部分eslint:recommended提到的规则在ivweb中没有提到，因此最好配合eslint:recommend一起使用。 55 | 56 | 只需要同时继承eslint:recommend 和 ivweb 即可，确保 ivweb 放置在最后。部分eslint:recommend定义的规则有点严格，ivweb里面有做定制化的修改。 57 | 58 | 第二步：增加precommit的hook和eslint-config-ivweb依赖 59 | 60 | 此处我们使用husky来管理所有的Hook，同之前的commit message校验。 61 | 62 | ``` 63 | { 64 | "name": "with-lint-staged", 65 | "version": "0.0.1", 66 | "scripts": { 67 | "precommit": "lint-staged" 68 | }, 69 | "lint-staged": { 70 | "src/*.{js,jsx}": [ 71 | "eslint --fix", 72 | "git add" 73 | ] 74 | }, 75 | "devDependencies": { 76 | "eslint": "^4.8.0", 77 | "eslint-plugin-react": "^7.4.0", 78 | "eslint-config-ivweb": "^0.1.0", 79 | "husky": "^0.14.3", 80 | "lint-staged": "^4.2.3" 81 | } 82 | } 83 | ``` 84 | 85 | ## 答疑互动 86 | 87 | Q： 为什么不直接使用airbnb团队的 eslint-config-airbnb？ 88 | A： airbnb官方的规则过于庞大，有10多个规则文件。维护起来成本较高，选择基于轻量级的 eslint:recommend 基础之上定制团队ESLint规则更加简单，也便于维护。 89 | 90 | Q： 我觉得eslint-config-ivweb有些规则不太合适，怎么办？ 91 | A： 欢迎提交issue讨论或者直接提交PR。仓库地址：https://github.com/feflow/eslint-config-ivweb 92 | 93 | Q： 为什么使用lint-staged？ 94 | A： lint-staged只会对修改过的js文件行数进行代码规范检查，不会对所有的代码检查，更加合理和可操作。 95 | -------------------------------------------------------------------------------- /index.js: -------------------------------------------------------------------------------- 1 | 'use strict';
