Storybook Addon Preview

Storybook Addon Preview 可以在 Storybook 中顯示使用者選擇的控制項（args）或旋鈕在各種框架程式碼中的樣子

開始使用

需要 Storybook 6 或更新版本。
如果您使用 Storybook 5，請使用 1.x 版本。

npm i storybook-addon-preview --dev

.storybook/main.js

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

現在，使用預覽撰寫您的 Stories。

如何搭配控制項（args）使用

安裝 @storybook/addon-controls

import { previewTemplate, DEFAULT_VANILLA_CODESANDBOX } from "storybook-addon-preview";
// CSF https://storybook.dev.org.tw/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,
    },
};

如何搭配旋鈕使用（已棄用）

安裝 @storybook/addon-knobs

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.dev.org.tw/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 範例

屬性

export interface PreviewParameter {
    /**
     * The name of the tab to appear in the preview panel
     */
    tab?: string;
    /**
     * Code to appear in the corresponding tab of the preview panel.
     */
    template?: string
    | ((props: Record<string, any>, globals: Record<string, any>) => any)
    | ReturnType<typeof previewTemplate>;
    /**
     * Description of the corresponding template code
     */
    description?: string;
    /**
     * Custom args or knobs that can be used in the preview template.
     */
    knobs?: Record<string, any>;
    /**
     * Custom args or knobs that can be used in the preview template.
     */
    args?: Record<string, any>;
    /**
     * Whether to display the copy button
     */
    copy?: boolean;
    /**
     * Language to highlight its code ("html", "css", "jsx", "tsx", "ts", "js")

     */
    continue?: boolean;
    /**
     * Formatting type for that code if you want formatting
     * Only "html" is supported as built-in support.
     * If you want to use custom formatter, use `previewFormatter` config in manager.js
     * @see {@link https://github.com/naver/storybook-addon-preview/blob/master/README.md}
     */
    format?: string | boolean;
}

格式化

Storybook 基本上使用 prettier 和 parser-html 的獨立版本。因此，PreviewParameter 格式僅支援「html」。

如果您使用自訂格式化程式，請注意檔案大小可能會增加。

請參閱：https://prettier.dev.org.tw/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",
            },
        ],
    }
}

範本

如果範本是不使用旋鈕的程式碼，您可以直接將其寫為 string 類型。

{
    template: `
const inst = new Instance({
    opt1: 1,
    num1: 1,
});
`,
}

如果您只是想按原樣表達旋鈕，請使用 previewTemplate 函式

import { previewTemplate } from "storybook-addon-preview";

{
    args: {
        args1: true,
    },
    template: previewTemplate`
const inst = new Instance({
    opt1: ${"opt1"},
    num1: ${"num1"},
    args1: ${"args1"},
});
`,
}

如果您想使用變數，請使用函式

{
    args: {
        args1: true,
    },
    template: (props, globals) => `
const inst = new Instance({
    opt1: ${props.opt1},
    num1: ${props.num1},
    args1: ${props.args1},
});
`,
}

醒目提示

如果您想醒目提示您的程式碼，請新增 [highlight] 註解。

[
    {
        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",
    },
]

如果您想醒目提示您的程式碼區塊，請新增 [highlight-start] 和 [highlight-end] 註解。

[
    {
        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",
    },
]

Props

當您有許多選項時，可以輕鬆使用選項或 props，或使用 props 範本

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

將您使用的程式碼連結到 CodeSandbox。有一個用於連結 CodeSandbox 的相依性和初始設定檔案。我們支援的框架包括 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"],
});

您可以使用預設的 CodeSandbox 預設值。

程式碼中使用的框架模組以外的外部模組

// DEFAULT_(VANILLA)_CODESANDBOX
// DEFAULT_(REACT)_CODESANDBOX
// DEFAULT_(ANGULAR)_CODESANDBOX
type DEFAULT_FRAMEWORK_CODESANDBOX: CodeSandboxTemplate = (userDependencies?: string[], files?: FilesParam) => CodeSandboxValue;

預覽中提供的 CodeSandbox 預設值為 vanilla、react、angular、vue、preact、lit 和 svelte。

            }),
        },
    ],
};

製作自訂 CodeSandbox

template 基於此邏輯。
dependencies、devDependencies、scripts 基於 package.json 的 dependencies、devDependencies、scripts
userDependencies 是陣列類型的相依性。（[vue@^2.6.0]）
files 具有 string、CodeFileTab（物件）和 null 類型。
- CodeFileTab：以字串值傳回預覽索引標籤。
- null：刪除現有檔案。

CodeSandbox 支援各種範本。若要使用該範本，您需要自行定義基本檔案。請參閱 CodeSandbox 中的範本。

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,
    };
};
