Description

When we want to retrieve the content of a Notion page, using the Notion API we will obtain a complex block structure(like this example). This package solves that structure and takes care of rendering that response.

Installation

``bash
npm i @9gustin/react-notion-render
`

Examples

$3

I would use the package @notionhq/client to get data from the Notion API and take this example of Notion Service also you can fetch the data from the api. This example take pages of an database an render the first of list. This example is an Page in Next.js.

`jsx
import { Render } from '@9gustin/react-notion-render'
import { getBlocks, getDatabase } from '../services/notion'

export default ({blocks}) =>

export const getStaticProps = async () => {
const DATABASE_ID = '54d0ff3097694ad08bd21932d598b93d'
const database = await getDatabase(DATABASE_ID)
const blocks = await getBlocks(database[0].id)

return {
props: {
blocks
}
}
}
`

I've maded a template to blog page, that use this package and allows you have a blog using notion as CMS.


📎 Repo: @9gustin/notion-blog-nextjs

📚 Notion Database: notion/notion-blog-nextjs

✨Web: blog-template


Note: My personal blog now it's using this template. Url: 9gustin.com

This example it's not maded by me, but i show you what package can do. This is a single page which use this package to render content

Usage

$3

You can override the package components, for example, if you want to use your own Code component or to replace native for NextImage. For this you have the prop blockComponentsMapper.

This works to use your own styles, a library of components (like Chackra UI, ANT Design) or better components than natives.

For example, if you want to use a custom H1:
`JSX
const MyHeading = ({plainText}) => {
return

H1! {plainText}


}
`

And in the render you pass the prop blockComponentsMapper like:
`JSX
heading_1: withContentValidation(MyHeading)
}} />
`

$3

blockComponentsMapper

It prop receives an json of type BlockComponentsMapperType, the keys represents the notion type:
https://github.com/9gustin/react-notion-render/blob/154e094e9477b5dada03358e2cecf695c06bb4d3/src/constants/BlockComponentsMapper/types.ts

And here the notion types enum(you can import it):
https://github.com/9gustin/react-notion-render/blob/feature/customBlockMapper/src/types/BlockTypes.ts

withContentValidation

I recommend that you import withContentValidation HOC from the package and wrap component on it, this HOC parse props and make it more clean, here the font-code:
https://github.com/9gustin/react-notion-render/blob/154e094e9477b5dada03358e2cecf695c06bb4d3/src/hoc/withContentValidation/index.tsx

I must work on a more clear documentation about this prop, but for now you can explore it.

$3

In Notion, page IDs are used to link between Notion pages. For example, if you link to a Notion page titled "Test" at notion.so/test-1a2b3c4d, the underlying markup will look like this:

`HTML



`

When building a website from Notion content, you may use a different logic for creating paths to access those Notion pages. For example, the page above may now be available at /test path. To rewrite /1a2b3c4d to /test, you can define your own function for mapping url and pass it to prop mapPageUrlFn of the Render component.

$3

If you followed the basic example, you may notice that the page are rendered without styles, only pure text. To solve that we can use the Render props, like the following cases.

#### Using default styles
This package give you default styles, colors, text styles(blod, italic) and some little things, if you want use have to add two things:

First import the stylesheet
`jsx
import '@9gustin/react-notion-render/dist/index.css'
`
And then add to the Render the prop useStyles, like that:
`jsx

`

And it's all, now the page looks some better, i tried to not manipulate that styles so much to preserve generic styles.

#### Using your own styles
If you want to add styles by your own, you can use the prop classNames, this props gives classes to the elements, it make more easier to identify them. For example to paragraphs give the class "rnr-paragraph", and you can add this class in your CSS and give styles.

`jsx

`
This is independient to the prop useStyles, you can combinate them or use separated.

The Render component has two more props that you can use.

#### Custom title url
With this package you can pin the titles in the url to share it. For example, if you have a title like My Title and you click it, the url looks like url.com#my-title. The function that parse the text it's here, you can check it. But if you want some diferent conversion you can pass a custom slugify function. In case that you want to separate characthers by _ instead of - yo can pass the slugifyFn prop:
`jsx
text.replace(/[^a-zA-Z0-9]/g,'_')} />
`
Or whatever you want, slugifyFn should receive and return a string.

If you dont want this functionality you can disable it with the prop simpleTitles:
`jsx

`

#### Preserve empty blocks
Now by default the Render component discard the empty blocks that you put in your notion page. If you want to preserve you can pass the prop emptyBlocks and it be rendered.
`jsx

`

The empty blocks contain the class "rnr-empty-block", this class has default styles (with useStyles) but you can apply your own styles.

$3

Now Notion API only supports text blocks, like h1, h2, h3, paragraph, lists(Notion Doc.). Custom components are here for you, it allows you to use other important blocks.

Important

The text to custom components sould be plain text, when you paste a link in Notion he convert to a link. You should convert it to plain text with the "Remove link" button. Like there:
!image

#### Link
Now you can use links like Markdown, links are supported by Notion API, but this add the possibility to made autorreference links, as an index.

Example:

`
Index:
1. Declarative
2. Component Based
3. About React
`
The link be maded with the slugifyFn, you can check the default, or pass a custom.

$3

⚠️ Now we support native notion images, if you add a image in your notion page this package would render it ;). This option would not be deprecated, just a suggestion.

This it simple, allows you to use images(includes GIF's). The syntax are the same like Markdown images. For it you have to include next text into your notion page as simple text

Example:

`
!My github profile pic
`

Plus

Also you can add a link to image, like an image anchor. This link would be opened when the user click the image. Thats works adding an # with the link after the markdown image.
`
!My github profile pic#https://github.com/9gustin
`
So when the user click my image in the blog it will be redirected to my github profile.


$3

⚠️ Now we support native notion videos, if you add a video in your notion page this package would render it ;). This option would not be deprecated, just a suggestion

You can embed Videos. You have 3 ways to embed a video.

- Local
- Youtube
- Google Drive (with a public share url)

Structure:

`
-title, or alternative text
`

Example:

`
-my youtube video
`




$3

Now we exporting the indexGenerator function, with that you can show a table of contents of your page content. This function receive a list of blocks and return only the title blocks. The structure of the result it's like:

!image

you can use it like that:
`jsx
import { indexGenerator, rnrSlugify } from '@9gustin/react-notion-render'

const TableOfContents = ({blocks}) => {
return (
<>
Table of contents:


{
indexGenerator(blocks).map(({ id, plainText, type }) => (

• 
  #${rnrSlugify(plainText)}}>
{plainText} - {type}



))
}


)
}

export default TableOfContents

`
if you want to add links use rnrSlugify or your custom slugify function to generate the href.

Contributions:

If you find a bug, or want to suggest a feature you can create a New Issue and will be analized. Contributions of any kind welcome!

In the repo we have a dev example, with this you can test what you are developing.

Clone repo and install package dependencies

`BASH
git clone https://github.com/9gustin/react-notion-render.git
cd react-notion-render
npm install
`

Run dev example to test added features. The example are in next.js, so have to install this dependency into dev-example folder.


IMPORTANT: Install dependencies of dev-example with npm install, not with yarn. This is because the dev-example uses parent node_modules (with file:../node_modules) and if install it with yarn it has problems with sub dependencies.

`BASH
cd dev-example
npm install
`

Add .env file with your notion token and run the example.

Inside of dev-example folder you find a .env.example file with the structure of .env file. Steps:
1. Go to notion.so/my-integrations and generate a new integration, copy the Internal Integration Token and paste it into the .env file wit the key NOTION_TOKEN.
2. Go to your notion, create a database that you want to use as example. Enter in it and copy the database id from url. https://www.notion.so/YOUR_PROFILE/DATABASE_ID?v=RANDOM
3. Share the database with the integration.

More detail in developers.notion.com/docs/getting-started

Starting the dev example

To run the dev example we must be in the root of the project, in the package.json we have the dev command, that starts package compiler and dev example together.
`BASH
cd .. //if we be inside of /dev-example
npm run dev
`

And voila. The app are running in port 3001 because a config in my pc, if you have problems with this you can change it in package.json, dev-example command

$3

In case you want to use another example to test what you are developing, please do the following:

1. In the package.json file of your example project, which can be located anywhere in your machine, link to the local version of react-notion-render:

`
"dependencies": {
"@9gustin/react-notion-render": "path/to-package"
}
`

This path can either be relative or absolute path.

2. Run npm install to install all the required packages for the example project, including the locally compiled version of react-notion-render.

3. Open a new terminal window and navigate to the react-notion-render. Run npm start to watch for changes you make to react-notion-render and build it on the go.

4. Go back to the terminal window with your example project and run npm run dev to test new changes of react-notion-render in the example.

src/components/core/Text | The text in notion are complex, this component contemplate text variants, like bold, italic. Also contemplate links.
src/hoc | Higher order components / in there we apply some logic rules.
src/hoc/withContentValidation | This HOC it's a filter before to pass the Notion block to the common components. almost every components are wrapped by this, and this objetive it's simplify props that the component would receive, applying package rules.
src/hoc/withCustomComponent | The package supports custom components. This HOC make it possible. before to render text validate if the text are a custom component and render it.
src/styles | package styles. We just use plain css, the objective it's not apply much style, just the necessary. We use :global() to avoid compile problems with the className
