@blocz/mdx-plugin-detect-imports

MDX plugin to detect the list of every imports done in a MDX file.

MDX 2

Since the v0.2.0, it's based on MDX v2. It you want to use it with MDX v1, you can look at the v0.1.0.
If you’re looking to upgrade to the v0.2.0, the list of breaking changes is listed here.

What does it do?

If your MDX file look like this:

import { Tabs, Button } from "@blocz/elements";

## Hello MDX

1. First item
2. Second item

<Button variant="blue" label="Label" />

This plugin will transform this file into:

import { Button, Tabs as Tabulations } from "@blocz/elements";

## Hello MDX

1. First item
2. Second item

<Button variant="blue" label="Label" />

export const importStatements = [
    {
        module: "@blocz/elements",
        imports: [
            {
                kind: "named",
                imported: "Button",
                local: "Button",
                value: this_is_the_value_of_the_variable_Button
            },
            {
                kind: "named",
                imported: "Tabs",
                local: "Tabulations",
                value: this_is_the_value_of_the_variable_Tabs
            }
        ]
    }

]

How to use

yarn add -D @blocz/mdx-plugin-detect-imports

Webpack

const detectImportsPlugin = require("@blocz/mdx-plugin-detect-imports");

module.exports = {
    // ...
    module: {
        rules: [
            // ...
            {
                test: /.mdx?$/,
                loader: "@mdx-js/loader",
                options: {
                    remarkPlugins: [detectImportsPlugin],
                    // Or if you want to specify a custom name for the exported variable:
                    remarkPlugins: [
                        [detectImportsPlugin, { exportName: "otherName" }],
                    ],
                },
            },
        ],
    },
};

And finally:

import MyAwesomeComponent, { importStatements } from './my-awesome-component.mdx'; (or import MyAwesomeComponent, { otherName } from './my-awesome-component.mdx'; if you specified a custom name.)

With MDX

import compile from "@mdx-js/mdx";
import detectImportsPlugin from "@blocz/mdx-plugin-detect-imports";

const vFile = await compile(mdxText, {
    remarkPlugins: [detectImportsPlugin],
});

// Or if you want to specify a custom name for the exported variable:

const vFile = await compile(mdxText, {
    remarkPlugins: [[detectImportsPlugin, { exportName: "otherName" }]],
});

type ImportStatement

If you need typings, we provide the following type:

interface ImportStatement {
    module: string;
    imports: Array<
        | {
              kind: "named";
              imported: string;
              local: string;
              value: any;
          }
        | {
              kind: "namespace" | "default";
              local: string;
              value: any;
          }
    >;
}

And then you can do:

// mdx.d.ts
declare module "*.mdx" {
    const MDXComponent: (props: any) => JSX.Element;
    // you can replace `importStatements` with your own variable name
    export const importStatements: ImportStatement[];
    export default MDXComponent;
}
