You may want to implement your own `<MultiLanguageCode />` abstraction if you find the above approach too verbose. We might just implement one in future for convenience.
If you have multiple of these multi-language code tabs, and you want to sync the selection across the tab instances, refer to the [Syncing tab choices section](markdown-features-tabs.mdx#syncing-tab-choices).
### Docusaurus npm2yarn remark plugin {#npm2yarn-remark-plugin}
Displaying CLI commands in both NPM and Yarn is a very common need, for example:
```bash npm2yarn
npm install @docusaurus/remark-plugin-npm2yarn
```
Docusaurus provides such a utility out of the box, freeing you from using the `Tabs` component every time. To enable this feature, first install the `@docusaurus/remark-plugin-npm2yarn` package as above, and then in `docusaurus.config.js`, for the plugins where you need this feature (doc, blog, pages, etc.), register it in the `remarkPlugins` option. (See [Docs configuration](../../api/plugins/plugin-content-docs.md#ex-config) for more details on configuration format)
```js title="docusaurus.config.js"
module.exports = {
// ...
presets: [
[
'@docusaurus/preset-classic',
{
docs: {
// highlight-start
remarkPlugins: [
[require('@docusaurus/remark-plugin-npm2yarn'), {sync: true}],
],
// highlight-end
},
pages: {
// highlight-next-line
remarkPlugins: [require('@docusaurus/remark-plugin-npm2yarn')],
},
blog: {
// ...
},
},
],
],
};
```
And then use it by adding the `npm2yarn` key to the code block:
````md
```bash npm2yarn
npm install @docusaurus/remark-plugin-npm2yarn
```
````
Using the `{sync: true}` option would make all tab choices synced. Because the choice is stored under the same namespace `npm2yarn`, different `npm2yarn` plugin instances would also sync their choices.
