Generate React CLI

依赖项许可证

Why?

帮助加快 React 项目的生产率,并在每次要创建新组件时停止复制、粘贴和重命名文件。

一些注意事项:

  • Now supports custom component types (read more). ????
  • Now supports custom component templates (read more). ????
  • Supports React TypeScript projects.
  • Supports two different component testing libraries - Testing Library and Enzyme - that work with Jest. We assume that you have these libraries already configured in your React project.
  • It follows grouping by feature because we believe when you look at a component, you should see all of its corresponding files (i.e., stylesheet, test, and component) under one folder with the feature name. We feel this approach provides a better developer experience.

You can run it using npx like this:

  npx generate-react-cli component Box

(npx 是 npm 5.2+ 自带的 package runner 工具)

Config File

当你第一次在你的项目中运行 GRC 时,它会问你一系列问题来为你的项目定制 cli需要(这将创建一个“generate-react-cli.json”配置文件)。

Example of the generate-react-cli.json config file:

{
  "usesTypeScript": false,
  "usesCssModule": true,
  "cssPreprocessor": "scss",
  "testLibrary": "Testing Library",
  "component": {
    "default": {
      "path": "src/components",
      "withLazy": false,
      "withStory": false,
      "withStyle": true,
      "withTest": true
    }
  }
}

Generate Components

  npx generate-react-cli component Box

此命令将在您的默认目录(例如 src/components)及其相应文件中创建一个文件夹,其中包含您的组件名称。

Example of the component files structure:

|-- /src
    |-- /components
        |-- /Box
            |-- Box.js
            |-- Box.css
            |-- Box.test.js

Options

您还可以使用一次性命令覆盖一些 GRC 组件配置规则。 例如,假设您在 component.default 属性中将 withTest 设置为 true。 您可以像这样覆盖它:

  npx generate-react-cli component Box --withTest=false

反之亦然,如果您已将 withTest 设置为 false,您可以这样做:

  npx generate-react-cli component Box --withTest=true

否则,如果您不传递任何选项,它将只使用您在 component.default 下的 GRC 配置文件中设置的默认值。

OptionsDescriptionValue TypeDefault Value
--pathValue of the path where you want the component to be generated in (e.g. src/components).Stringcomponent.default.path
--typeYou can pass a custom component type that you have configured in the GRC config file that has its own set of component config rules. Read more about custom component types.Stringcomponent.default
--withLazyCreates a corresponding lazy file (a file that lazy-loads your component out of the box and enables code splitting) with this component.Booleancomponent.default.withLazy
--withStoryCreates a corresponding (storybook) story file with this component.Booleancomponent.default.withStory
--withStyleCreates a corresponding stylesheet file with this component.Booleancomponent.default.withStyle
--withTestCreates a corresponding test file with this component.Booleancomponent.default.withTest

Custom component types:

默认情况下,GRC 在开箱即用地运行组件命令时将使用 component.default 配置规则。

如果您想生成具有自己的一组配置规则(例如,页面布局)的其他类型的组件怎么办?

您可以像这样扩展 generate-react-cli.json 配置文件来做到这一点。

{
  "usesTypeScript": false,
  "usesCssModule": true,
  "cssPreprocessor": "scss",
  "testLibrary": "Testing Library",
  "component": {
    "default": {
      "path": "src/components",
      "withLazy": false,
      "withStory": false,
      "withStyle": true,
      "withTest": true
    },
    "page": {
      "path": "src/pages",
      "withLazy": true,
      "withStory": false,
      "withStyle": true,
      "withTest": true
    },
    "layout": {
      "path": "src/layout",
      "withLazy": false,
      "withStory": false,
      "withStyle": false,
      "withTest": true
    }
  }
}

现在您可以像这样使用您的自定义组件类型生成一个组件:

  npx generate-react-cli component HomePage --type=page
  npx generate-react-cli component BoxLayout --type=layout

您还可以将相同的选项传递给您的自定义组件类型,就像您对默认组件类型所做的那样。

Custom component templates

你也可以创建自己的自定义模板,GRC 可以使用它来代替它自带的内置模板。 我们希望这将为您要生成的组件提供更大的灵活性。

有一个可选的 customTemplates 对象,您可以将其传递给 component.defaultgenerate-react-cli.json配置文件。

Example of the customTemplates object:

"customTemplates": {
  "component": "templates/component.js",
  "lazy":  "templates/lazy.js",
  "story":  "templates/story.js",
  "style": "templates/style.scss",
  "test":  "templates/test.js"
},

键代表模板的类型,值是指向自定义模板在项目/系统中所在位置的路径。

Example of using the customTemplates object within your generate-react-cli.json config file:

{
  "usesTypeScript": false,
  "usesCssModule": true,
  "cssPreprocessor": "scss",
  "testLibrary": "Testing Library",
  "component": {
    "default": {
      "customTemplates": {
        "component": "templates/component/component.js",
        "style": "templates/component/style.scss",
        "test": "templates/component/test.js"
      },
      "path": "src/components",
      "withStyle": true,
      "withTest": true,
      "withStory": true,
      "withLazy": false
    },
    "page": {
      "customTemplates": {
        "test": "templates/page/test.js"
      },
      "path": "src/pages",
      "withLazy": true,
      "withStory": false,
      "withStyle": true,
      "withTest": true
    }
  }
}

请注意,在 page.customTemplates 中,我们只指定了 test 自定义模板类型。 那是因为所有自定义模板类型都是可选的。 如果你不设置其他类型,GRC会默认使用它自带的内置模板。

Example of a custom component template file:

// templates/component/component.js

import React from 'react';
import styles from './TemplateName.module.css';

const TemplateName = () => (
  <div className={styles.TemplateName} data-testid="TemplateName">
    <h1>TemplateName component</h1>
  </div>
);

export default TemplateName;

重要 - 确保在模板中使用 TemplateName 关键字。 GRC 将使用此关键字将其替换为您的组件名称。

Example of a custom test template file:

// templates/component/test.js

import React from 'react';
import ReactDOM from 'react-dom';
import TemplateName from './TemplateName';

it('It should mount', () => {
  const div = document.createElement('div');
  ReactDOM.render(<TemplateName />, div);
  ReactDOM.unmountComponentAtNode(div);
});

Why?

To help speed up productivity in React projects and stop copying, pasting, and renaming files each time you want to create a new component.

A few notes:

  • Now supports custom component types (read more). ????
  • Now supports custom component templates (read more). ????
  • Supports React TypeScript projects.
  • Supports two different component testing libraries - Testing Library and Enzyme - that work with Jest. We assume that you have these libraries already configured in your React project.
  • It follows grouping by feature because we believe when you look at a component, you should see all of its corresponding files (i.e., stylesheet, test, and component) under one folder with the feature name. We feel this approach provides a better developer experience.

You can run it using npx like this:

  npx generate-react-cli component Box

(npx is a package runner tool that comes with npm 5.2+)

Config File

When you run GRC within your project the first time, it will ask you a series of questions to customize the cli for your project needs (this will create a "generate-react-cli.json" config file).

Example of the generate-react-cli.json config file:

{
  "usesTypeScript": false,
  "usesCssModule": true,
  "cssPreprocessor": "scss",
  "testLibrary": "Testing Library",
  "component": {
    "default": {
      "path": "src/components",
      "withLazy": false,
      "withStory": false,
      "withStyle": true,
      "withTest": true
    }
  }
}

Generate Components

  npx generate-react-cli component Box

This command will create a folder with your component name within your default (e.g. src/components) directory, and its corresponding files.

Example of the component files structure:

|-- /src
    |-- /components
        |-- /Box
            |-- Box.js
            |-- Box.css
            |-- Box.test.js

Options

You can also override some of the GRC component config rules using one-off commands. So for example, let's say you have set withTest to be true in the component.default property. You can override it like this:

  npx generate-react-cli component Box --withTest=false

Or vice versa, if you have set withTest to be false you can do this:

  npx generate-react-cli component Box --withTest=true

Otherwise, if you don't pass any options, it will just use the default values that you have set in the GRC config file under component.default.

OptionsDescriptionValue TypeDefault Value
--pathValue of the path where you want the component to be generated in (e.g. src/components).Stringcomponent.default.path
--typeYou can pass a custom component type that you have configured in the GRC config file that has its own set of component config rules. Read more about custom component types.Stringcomponent.default
--withLazyCreates a corresponding lazy file (a file that lazy-loads your component out of the box and enables code splitting) with this component.Booleancomponent.default.withLazy
--withStoryCreates a corresponding (storybook) story file with this component.Booleancomponent.default.withStory
--withStyleCreates a corresponding stylesheet file with this component.Booleancomponent.default.withStyle
--withTestCreates a corresponding test file with this component.Booleancomponent.default.withTest

Custom component types:

By default, GRC will use the component.default configuration rules when running the component command out of the box.

What if you wanted to generate other types of components that have their own set of config rules (e.g., page or layout)?

You can do so by extending the generate-react-cli.json config file like this.

{
  "usesTypeScript": false,
  "usesCssModule": true,
  "cssPreprocessor": "scss",
  "testLibrary": "Testing Library",
  "component": {
    "default": {
      "path": "src/components",
      "withLazy": false,
      "withStory": false,
      "withStyle": true,
      "withTest": true
    },
    "page": {
      "path": "src/pages",
      "withLazy": true,
      "withStory": false,
      "withStyle": true,
      "withTest": true
    },
    "layout": {
      "path": "src/layout",
      "withLazy": false,
      "withStory": false,
      "withStyle": false,
      "withTest": true
    }
  }
}

Now you can generate a component with your custom component types like this:

  npx generate-react-cli component HomePage --type=page
  npx generate-react-cli component BoxLayout --type=layout

You can also pass the same options to your custom component types as you would for the default component type.

Custom component templates

You can also create your own custom templates that GRC can use instead of the built-in templates that come with it. We hope this will provide more flexibility for your components that you want to generate.

There is an optional customTemplates object that you can pass to the component.default or any of your custom component types within your generate-react-cli.json config file.

Example of the customTemplates object:

"customTemplates": {
  "component": "templates/component.js",
  "lazy":  "templates/lazy.js",
  "story":  "templates/story.js",
  "style": "templates/style.scss",
  "test":  "templates/test.js"
},

The keys represent the type of template, and the values are the paths that point to where your custom template lives in your project/system.

Example of using the customTemplates object within your generate-react-cli.json config file:

{
  "usesTypeScript": false,
  "usesCssModule": true,
  "cssPreprocessor": "scss",
  "testLibrary": "Testing Library",
  "component": {
    "default": {
      "customTemplates": {
        "component": "templates/component/component.js",
        "style": "templates/component/style.scss",
        "test": "templates/component/test.js"
      },
      "path": "src/components",
      "withStyle": true,
      "withTest": true,
      "withStory": true,
      "withLazy": false
    },
    "page": {
      "customTemplates": {
        "test": "templates/page/test.js"
      },
      "path": "src/pages",
      "withLazy": true,
      "withStory": false,
      "withStyle": true,
      "withTest": true
    }
  }
}

Notice in the page.customTemplates that we only specified the test custom template type. That's because all the custom template types are optional. If you don't set the other types, GRC will default to using the built-in templates it comes with.

Example of a custom component template file:

// templates/component/component.js

import React from 'react';
import styles from './TemplateName.module.css';

const TemplateName = () => (
  <div className={styles.TemplateName} data-testid="TemplateName">
    <h1>TemplateName component</h1>
  </div>
);

export default TemplateName;

Important - Make sure to use the TemplateName keyword in your templates. GRC will use this keyword to replace it with your component name.

Example of a custom test template file:

// templates/component/test.js

import React from 'react';
import ReactDOM from 'react-dom';
import TemplateName from './TemplateName';

it('It should mount', () => {
  const div = document.createElement('div');
  ReactDOM.render(<TemplateName />, div);
  ReactDOM.unmountComponentAtNode(div);
});
