Avisos (Admonitions)

In addition to the basic Markdown syntax, we have a special admonitions syntax by wrapping text with a set of 3 colons, followed by a label denoting its type.

Exemplo:

:::note

Some **content** with _Markdown_ `syntax`. Check [this `api`](#).

:::

:::tip

Some **content** with _Markdown_ `syntax`. Check [this `api`](#).

:::

:::info

Some **content** with _Markdown_ `syntax`. Check [this `api`](#).

:::

:::warning

Some **content** with _Markdown_ `syntax`. Check [this `api`](#).

:::

:::danger

Some **content** with _Markdown_ `syntax`. Check [this `api`](#).

:::
http://localhost:3000
note

Some content with Markdown syntax. Check this api.

tip

Some content with Markdown syntax. Check this api.

info

Some content with Markdown syntax. Check this api.

warning

Some content with Markdown syntax. Check this api.

danger

Some content with Markdown syntax. Check this api.

Usage with Prettier

If you use Prettier to format your Markdown files, Prettier might auto-format your code to invalid admonition syntax. To avoid this problem, add empty lines around the starting and ending directives. This is also why the examples we show here all have empty lines around the content.

<!-- Prettier doesn't change this -->
:::note

Hello world

:::

<!-- Prettier changes this -->
:::note
Hello world
:::

<!-- to this -->
::: note Hello world:::

Specifying title

You may also specify an optional title.

:::note[Your Title **with** some _Markdown_ `syntax`!]

Some **content** with some _Markdown_ `syntax`.

:::
http://localhost:3000
Your Title with some Markdown syntax!

Some content with some Markdown syntax.

Nested admonitions

Admonitions can be nested. Use more colons : for each parent admonition level.

:::::info[Parent]

Parent content

::::danger[Child]

Child content

:::tip[Deep Child]

Deep child content

:::

::::

:::::
http://localhost:3000
Parent

Parent content

Child

Child content

Deep Child

Deep child content

Admonitions with MDX

Você também pode usar MDX dentro de admoestações!

import Tabs from '@theme/Tabs';

import TabItem from '@theme/TabItem';

:::tip[Use tabs in admonitions]

<Tabs>
<TabItem value="apple" label="Apple">This is an apple 🍎</TabItem>
<TabItem value="orange" label="Orange">This is an orange 🍊</TabItem>
<TabItem value="banana" label="Banana">This is a banana 🍌</TabItem>
</Tabs>

:::
http://localhost:3000
Use tabs in admonitions
This is an apple 🍎

Usage in JSX

Outside of Markdown, you can use the @theme/Admonition component to get the same output.

MyReactPage.jsx
import Admonition from '@theme/Admonition';

export default function MyReactPage() {
return (
<div>
<Admonition type="info">
<p>Some information</p>
</Admonition>
</div>
);
}

The types that are accepted are the same as above: note, tip, danger, info, warning. Optionally, you can specify an icon by passing a JSX element or a string, or a title:

MyReactPage.jsx
<Admonition type="tip" icon="💡" title="Did you know...">

elements in your project.
</Admonition>
http://localhost:3000
💡Did you know...

Customizing admonitions

There are two kinds of customizations possible with admonitions: parsing and rendering.

Customizing rendering behavior

You can customize how each individual admonition type is rendered through swizzling. You can often achieve your goal through a simple wrapper. For example, in the follow example, we swap out the icon for info admonitions only.

src/theme/Admonition.js
import React from 'react';
import Admonition from '@theme-original/Admonition';
import MyCustomNoteIcon from '@site/static/img/info.svg';

export default function AdmonitionWrapper(props) {
if (props.type !== 'info') {
return <Admonition title="My Custom Admonition Title" {...props} />;
}
return <Admonition icon={<MyCustomNoteIcon />} {...props} />;
}

Customizing parsing behavior

Admonitions are implemented with a Remark plugin. The plugin is designed to be configurable. To customize the Remark plugin for a specific content plugin (docs, blog, pages), pass the options through the admonitions key.

docusaurus.config.js
export default {
presets: [
[
'@docusaurus/preset-classic',
{
docs: {
admonitions: {
keywords: ['note', 'tip', 'info', 'warning', 'danger'],
extendDefaults: true,
},
},
},
],
],
};

The plugin accepts the following options:

  • keywords: An array of keywords that can be used as the type for the admonition.
  • extendDefaults: Should the provided options (such as keywords) be merged into the existing defaults. Defaults to true.

The keyword will be passed as the type prop of the Admonition component.

Custom admonition type components

By default, the theme doesn't know what do to with custom admonition keywords such as :::my-custom-admonition. It is your responsibility to map each admonition keyword to a React component so that the theme knows how to render them.

If you registered a new admonition type my-custom-admonition via the following config:

docusaurus.config.js
export default {
// ...
presets: [
[
'classic',
{
// ...
docs: {
admonitions: {
keywords: ['my-custom-admonition'],
extendDefaults: true,
},
},
},
],
],
};

You can provide the corresponding React component for :::my-custom-admonition by creating the following file (unfortunately, since it's not a React component file, it's not swizzlable):

src/theme/Admonition/Types.js
import React from 'react';
import DefaultAdmonitionTypes from '@theme-original/Admonition/Types';

function MyCustomAdmonition(props) {
return (
<div style={{border: 'solid red', padding: 10}}>
<h5 style={{color: 'blue', fontSize: 30}}>{props.title}</h5>
<div>{props.children}</div>
</div>
);
}

const AdmonitionTypes = {
...DefaultAdmonitionTypes,

// Add all your custom admonition types here...
// You can also override the default ones if you want
'my-custom-admonition': MyCustomAdmonition,
};

export default AdmonitionTypes;

Now you can use your new admonition keyword in a Markdown file, and it will be parsed and rendered with your custom logic:

:::my-custom-admonition[My Title]

It works!

:::
http://localhost:3000
My Title

It works!
