npm version

Storybook Addon Preview 可以在 Storybook 中显示用户选择的 controls(args)knobs 在各种框架代码中。

入门

  • 需要 Storybook 6 或更高版本。
  • 如果您使用 Storybook 5,请使用 1.x 版本。
npm i storybook-addon-preview --dev

.storybook/main.js

module.exports = {
    addons: [
        "storybook-addon-preview/register"
    ],
};

现在,使用预览编写您的故事。

如何与 controls(args) 一起使用

import { previewTemplate, DEFAULT_VANILLA_CODESANDBOX } from "storybook-addon-preview";
// CSF https://storybook.org.cn/docs/react/api/csf

export default {
    title: "Example",
}
export const example = e => {
    e.opt1;
    e.num1;
    return ....;
}
example.parameters = {
    preview: [
        {
            tab: "Vanilla",
            template: previewTemplate`
const inst = new Instance({
    opt1: ${"opt1"},
    num1: ${"num1"},
});
            `,
            language: "ts",
            copy: true,
            codesandbox: DEFAULT_VANILLA_CODESANDBOX(["@egjs/infinitegrid"]),
        },
    ],
};
example.args = {
    opt1: false,
    num1: 0,
};
example.argTypes = {
    opt1: {
        control: { type: "boolean" },
        defaultValue: false,
    },
    num1: {
        control: { type: "number" },
        defaultValue: 0,
    },
};

如何与 knobs 一起使用(已弃用)

import { withPreview, previewTemplate, DEFAULT_VANILLA_CODESANDBOX } from "storybook-addon-preview";
import { withKnobs, boolean, number } from "@storybook/addon-knobs";

const stories = storiesOf("Example", module);

stories.addDecorator(withKnobs).addDecorator(withPreview);

stories.add("example", e => {
    const opt1Value = boolean("opt1", false);
    const num1Value = number("num1", 0);

    return ....;
}, {
    preview: [
        {
            tab: "Vanilla",
            template: previewTemplate`
const inst = new Instance({
    opt1: ${"opt1"},
    num1: ${"num1"},
});
            `,
            language: "ts",
            copy: true,
            codesandbox: DEFAULT_VANILLA_CODESANDBOX(["@egjs/infinitegrid"]),
        },
    ]
});
// CSF https://storybook.org.cn/docs/react/api/csf

export default {
    title: "Example",
    decorators: [withKnobs, withPreview],
    parameters: {
        preview: [
            {
                tab: "Vanilla",
                template: previewTemplate`
    const inst = new Instance({
        opt1: ${"opt1"},
        num1: ${"num1"},
    });
                `,
                language: "ts",
                copy: true,
                codesandbox: DEFAULT_VANILLA_CODESANDBOX(["@egjs/infinitegrid"]),
            },
        ],
    },
}
export const example = e => {
    const opt1Value = boolean("opt1", false);
    const num1Value = number("num1", 0);

    return ....;
}

InfiniteGrid 的 Storybook 示例

     */
    format?: string | boolean;
}

格式化

Storybook 主要使用 prettierparser-html 的独立版本。因此,PreviewParameter 格式仅支持“html”。

如果您使用自定义格式化程序,请注意文件大小可能会增加。

参见:https://prettier.node.org.cn/docs/en/browser.html

// .storybook/manager.js
import { addons } from "@storybook/addons";
import * as prettier from "prettier/standalone";
import * as htmlParser from "prettier/parser-html";
import * as babelParser from "prettier/parser-babel";
import * as postCSSParser from "prettier/parser-postcss";

addons.setConfig({
    previewFormatter: (format, code) => {
        if (format === "tsx") {
            return prettier.format(code, {
                parser: "babel-ts",
                plugins: [
                    htmlParser,
                    babelParser,
                    postCSSParser,
                ],
            });
        } else if (format === "vue") {
            return prettier.format(code, {
                parser: "vue",
                plugins: [
                    htmlParser,
                    babelParser,
                    postCSSParser,
                ],
            });
        }
        return code;
    },
});
// stories.js

export const Story = {
    parameters: {
        preview: [
            {
                tab: "Vanilla",
                template: `
const inst = new Instance({
    opt1: "opt1",
    num1: "num1",
});
                `,
                language: "ts",
                format: "tsx",
            },
        ],
    }
}

模板

  • 如果模板是不使用旋钮的代码,您可以将其简单地编写为 string 类型。
{
    template: `
const inst = new Instance({
    opt1: 1,
    num1: 1,
});
`,
}
  • 如果您只想按原样表达旋钮,请使用 previewTemplate 函数
import { previewTemplate } from "storybook-addon-preview";

{
    args: {
        args1: true,
    },
    template: previewTemplate`
const inst = new Instance({
    opt1: ${"opt1"},
    num1: ${"num1"},
    args1: ${"args1"},
});
`,
}
  • 如果您想使用变量,请使用函数
{
    args: {
        args1: true,
    },
    template: (props, globals) => `
const inst = new Instance({
    opt1: ${props.opt1},
    num1: ${props.num1},
    args1: ${props.args1},
});
`,
}

高亮

  • 如果要突出显示代码,请添加 [highlight] 注释。
[
    {
        template: previewTemplate`
    const inst = new Instance({
        /* [highlight] highlight opt1 */
        opt1: ${"opt1"},
        num1: ${"num1"},
    });
        `,
        language: "js",
    },
    {
        template: previewTemplate`
<!-- [highlight] highlight html -->
<div style="width: ${"width"}px;"></div>
        `,
        language: "html",
    },
]
  • 如果要突出显示代码区域,请添加 [highlight-start][highlight-end] 注释。
[
    {
        template: previewTemplate`
    const inst = new Instance({
        /* [highlight-start] highlight options */
        opt1: ${"opt1"},
        num1: ${"num1"},
        /* [highlight-end] */
    });
    `,
    },
    {
        template: previewTemplate`
<!-- [highlight-start] highlight html -->
<div style="width: ${"width"}px;"></div>
<!-- [highlight-end] -->
        `,
        language: "html",
    },
]

属性

当您有很多选项时,可以轻松地使用选项或属性或使用属性模板。

export interface PropsOptions {
    indent?: number;
    wrap?: string;
    prefix?: string;
}
  • DEFAULT_PROPS_TEMPLATE(names: string[], options: PropsOptions)
import { previewTemplate, DEFAULT_PROPS_TEMPLATE } from "storybook-addon-preview";

{
    template: previewTemplate`
/* [highlight] You can see opt1, num1 options. */
const inst = new Instance({
${DEFAULT_PROPS_TEMPLATE(["opt1", "num1"], { indent: 4 })}
});
`,
}
  • JSX_PROPS_TEMPLATE(names: string[], options: PropsOptions)
import { previewTemplate, JSX_PROPS_TEMPLATE } from "storybook-addon-preview";

{
    template: previewTemplate`
/* [highlight] You can see opt1, num1 options. */
<Instance
${JSX_PROPS_TEMPLATE(["opt1", "num1"], { indent: 4 })}
    />
`,
    language: "jsx",
}
  • ANGULAR_PROPS_TEMPLATE(names: string[], options: PropsOptions)
import { previewTemplate, ANGULAR_PROPS_TEMPLATE } from "storybook-addon-preview";

{
    template: previewTemplate`
/* [highlight] You can see opt1, num1 options. */
<ngx-instance
${ANGULAR_PROPS_TEMPLATE(["opt1", "num1"], { indent: 4 })}
    ></ngx-instance>
`,
    language: "html",
}
  • VUE_PROPS_TEMPLATE(names: string[], options: PropsOptions)
import { previewTemplate, VUE_PROPS_TEMPLATE } from "storybook-addon-preview";

{
    template: previewTemplate`
/* [highlight] You can see opt1, num1 options. */
<vue-instance
${VUE_PROPS_TEMPLATE(["opt1", "num1"], { indent: 4 })}
    ></vue-instance>
`,
    language: "html",
}
  • LIT_PROPS_TEMPLATE(names: string[], options: PropsOptions)
import { previewTemplate, LIT_PROPS_TEMPLATE } from "storybook-addon-preview";

{
    template: previewTemplate`
/* [highlight] You can see opt1, num1 options. */
html${"`"}<lit-instance
${LIT_PROPS_TEMPLATE(["opt1", "num1"], { indent: 4 })}
    ></lit-instance>${"`"};
`,
    language: "js",
}

CodeSandBox

将您使用的代码链接到代码沙箱。有一个依赖项和初始设置文件用于链接代码沙箱。我们支持的框架包括 React、Angular、Svelte、Lit、Preact 和 Vue。

const CodeSandboxValue = {
    // https://github.com/codesandbox/codesandbox-importers/blob/master/packages/import-utils/src/create-sandbox/templates.ts#L63
    template: "vue-cli",
    files: {
        "src/main.js": `
import Vue from "vue";
import App from "./App.vue";

Vue.config.productionTip = false;

new Vue({
render: h => h(App)
}).$mount("#app");
    `,
        "src/App.vue": {
            tab: "Vue",
        },
    },
    dependencies: {
        "vue": "^2.6.0",
    },
    userDependencies: ["@egjs/vue-infinitegrid@^3"],
});

您可以使用默认的 codesandbox 预设。

  • 代码中使用的除框架模块之外的外部模块
// DEFAULT_(VANILLA)_CODESANDBOX
// DEFAULT_(REACT)_CODESANDBOX
// DEFAULT_(ANGULAR)_CODESANDBOX
type DEFAULT_FRAMEWORK_CODESANDBOX: CodeSandboxTemplate = (userDependencies?: string[], files?: FilesParam) => CodeSandboxValue;
  • 预览中提供的 codesandbox 预设为 vanilla、react、angular、vue、preact、lit 和 svelte。

            tab: "HTML",
            template: ...,
        },
        {
            // { tab: "CSS" }
            tab: "CSS",
            template: ...,
        },
        {
            // { tab: "Vanilla" }
            tab: "Vanilla",
            template: ...,
            codesandbox: DEFAULT_VANILLA_CODESANDBOX(["@egjs/infinitegrid"]),
        },
        {
            // { tab: "React" }
            tab: "React",
            template: ...,
            codesandbox: DEFAULT_REACT_CODESANDBOX(["@egjs/react-infinitegrid"]),
        },
        {
            // { tab: "Angular", index: 0 }
            tab: "Angular",
            description: "app.component.html",
            template: ...,
            language: "markup",
            codesandbox: DEFAULT_ANGULAR_CODESANDBOX(["@egjs/ngx-infinitegrid"]),
        },
        {
            // { tab: "Angular", index: 1 }
            tab: "Angular",
            description: "app.component.ts",
            template: ...,
            language: "tsx",
            codesandbox: DEFAULT_ANGULAR_CODESANDBOX(["@egjs/ngx-infinitegrid"]),
        },
        {
            // { tab: "Angular", index: 2 }
            tab: "Angular",
            description: "app.module.ts",
            template: ...,
            language: "typescript",
            codesandbox: DEFAULT_ANGULAR_CODESANDBOX(["@egjs/ngx-infinitegrid"]),
        },
    ],
}

更改选项卡名称

检查代码沙箱预设代码以获取文件名。

import {
    DEFAULT_VANILLA_CODESANDBOX,
    DEFAULT_REACT_CODESANDBOX,
    DEFAULT_ANGULAR_CODESANDBOX,
} from "storybook-addon-preview";

{
    preview: [
        {
            tab: "Custom HTML",
            template: ...,
        },
        {
            tab: "Custom CSS",
            template: ...,
        },
        {
            tab: "Vanilla",
            template: ...,
            codesandbox: DEFAULT_VANILLA_CODESANDBOX(["@egjs/infinitegrid"], {
                "index.html": {
                    tab: "Custom HTML",
                    template: "html",
                    values: {
                        cssFiles: ["src/styles.css"],
                        jsFiles: ["src/index.ts"],
                    },
                },
                "src/styles.css" : { tab: "Custom CSS" },
            }),
        },
        {
            tab: "Angular Component HTML",
            description: "app.component.html",
            template: ...,
            language: "markup",
            codesandbox: DEFAULT_ANGULAR_CODESANDBOX(["@egjs/ngx-infinitegrid"], {
                "src/app/app.component.html": { tab: "Angular Component HTML" },
                "src/app/app.component.ts": { tab: "Angular Component" },
                "src/app/app.module.ts": { tab: "Angular Module" },
            }),
        },
        {
            tab: "Angular Component",
            description: "app.component.ts",
            template: ...,
            language: "tsx",
            codesandbox: DEFAULT_ANGULAR_CODESANDBOX(["@egjs/ngx-infinitegrid"], {
                "src/app/app.component.html": { tab: "Angular Component HTML" },
                "src/app/app.component.ts": { tab: "Angular Component" },
                "src/app/app.module.ts": { tab: "Angular Module" },
            }),
        },
        {
            tab: "Angular Module",
            description: "app.module.ts",
            template: ...,
            language: "typescript",
            codesandbox: DEFAULT_ANGULAR_CODESANDBOX(["@egjs/ngx-infinitegrid"], {
                "src/app/app.component.html": { tab: "Angular Component HTML" },
                "src/app/app.component.ts": { tab: "Angular Component" },
                "src/app/app.module.ts": { tab: "Angular Module" },
            }),
        },
    ],
};

创建自定义 CodeSandbox

  • template 基于 逻辑。
  • dependenciesdevDependenciesscripts 基于 package.jsondependenciesdevDependenciesscripts
  • userDependencies 是数组类型的依赖项。([vue@^2.6.0])
  • files 具有字符串、CodeFileTab(对象) 和 null 类型。
    • CodeFileTab:将预览选项卡作为字符串值返回。
    • null:删除现有文件。

CodeSandbox 支持各种模板。要使用模板,您需要自己定义基本文件。请参阅 CodeSandbox 中的模板。

export const DEFAULT_VUE_CODESANDBOX: CodeSandboxTemplate = (userDependencies = [], files = {}) => {
    return {
        template: "vue-cli",
        files: {
            "src/main.js": `
import Vue from "vue";
import App from "./App.vue";

Vue.config.productionTip = false;

new Vue({
    render: h => h(App)
}).$mount("#app");
        `,
            "src/App.vue": {
                tab: "Vue",
            },
            ...files,
        },
        dependencies: {
            "vue": "^2.6.0",
        },
        userDependencies,
    };
};
