@blocz/mdx-plugin-detect-imports v0.3.0

@blocz/mdx-plugin-detect-imports

TL;DR

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

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
    // this is a comment
    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: [
            {
                imported: "Button",
                local: "Button",
                value: this_is_the_value_of_the_variable_Button
            },
            {
                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

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

const jsx = await mdx(mdxText, {
    remarkPlugins: [detectImportsPlugin],
});

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

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

type ImportStatement

If you need typings, we provide the following type:

interface ImportStatement {
    module: string;
    imports: Array<{
        imported: string;
        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;
}
