Gatsby Source Plugin Notion API

Gatsby source plugin for working with official Notion API.

Here's a Postman collection to play around with the API if you're interested: https://www.postman.com/notionhq/workspace/notion-s-public-api-workspace/overview

🚧 It's a work in progress

This is a source plugin for pulling content into Gatsby from official public Notion API (currently in beta). With this plugin, you will be able to query your Notion pages in Gatsby using GraphQL.

Notion API Reference

How to use

Before using this plugin, make sure you

1. Created a Notion integration (sign in to Notion, go to Settings & Memberships → Integrations → Develop your own integrations, short link to the Integrations creation section). It's OK to use an internal one. Don't forget to copy the token:
2. Go to the database you want to have access to from Gatsby, and share it with the integration (Share → Select the integration in the Invite dropdown). Don't forget the database in the URL. It's a series of characters after the last slash and before the question mark. Here's a reference: https://www.notion.so/{USER}/**{DATABASE_ID}**?{someotherirrelevantstuff}

Then add this to your gatsby-config.json:

plugins: [
    {
        resolve: `gatsby-source-notion-api`,
        options: {
            token: `$INTEGRATION_TOKEN`,
            databaseId: `$DATABASE_ID`,
            propsToFrontmatter: true,
            lowerTitleLevel: true,
        },
    },
    // ...
]

Configuration options

token [string][required]

Integration token.

databaseId [string][required]

The identifier of the database you want to get pages from. The integration identified by provided token must have access to the database with given id.

propsToFrontmatter [boolean][defaults to true]

Put Notion page props to Markdown frontmatter. If you set this to false, you will need to query notion to get page props.

lowerTitleLevel [boolean][defaults to true]

Push headings one level down. # becomes ##, ## becomes ###, ### becomes ####. Notion is limited to only 3 levels of heading. You can create ####, #####, etc. - they will not be reflected in Notion, but they will work properly in the Markdown output. Is true by default.

How to query for nodes

You can query for pages with notion or grab all of them with allNotion. The raw content of the page is available under raw property.

Query for all nodes

query {
    allNotion {
        edges {
            node {
                id
                parent
                children
                internal
                title
                properties {
                    My_Prop_1
                    My_Prop_2
                }
                archived
                createdAt
                updatedAt
                markdown
                raw
            }
        }
    }
}

Alternatively, you can use MarkdownRemark or MDX directly:

query {
    allMarkdownRemark {
        edges {
            node {
                frontmatter {
                    title
                }
                html
            }
        }
    }
}

Node properties

id

Unique page identifier. This is not a Notion page identifier. You can get the Notion page id under raw.id.

parent (Node)

Parend Node.

children

Blocks that belong to the page.

title (String)

Page title joined into one string.

properties

Properties of the page. An object with keys representing database columns (snake-cased), and the following value:

id (String)

Notion column id

key (String)

Readable name of the column (without snake case).

value (*)

Value of the column for the page. Might have different structure depending on the type.

type (String)

Notion type of the column.

archived (Boolean)

Boolean. Is true if the pages was marked removed but not removed permanently.

createdAt (Date)

Date of page creation.

updatedAt (Date)

Date of the last page update.

raw (*)

Untouched contents of whatever Notion API returned.

markdown (String)

Markdown contents of the page. Limited by blocks currently supported by Notion API. Unsupported blocks turn into HTML comments specifying that Notion marked this block as non-supported.

Since there's not semantic HTML analog for column lists and columns, these Notion blocks are transformed to <ColumnList> and <Column> components in the markdown. To customize these components, you can write custom components for these and include them in your MDXProvider.

Attaching images via "Files" property

If you want to turn images attached through the "Files" property into file nodes that you can use with gatsby-image, you need to attach remote file nodes to the "Files" property. In the example below, the propsToFrontmatter is set to true and the Hero Image Files property is used for images:

// ./gatsby-node.js
exports.onCreateNode = async ({ node, actions: { createNode }, createNodeId, getCache }) => {
    if (node.internal.type === "MarkdownRemark") {
        for (let i = 0; i < node.frontmatter["Hero Image"].length; i++) {
            const name = node.frontmatter["Hero Image"][i].name

            if (!name) {
                continue
            }

            if (name.startsWith("http")) {
                const fileNode = await createRemoteFileNode({
                    url: name,
                    parentNodeId: node.id,
                    createNode,
                    createNodeId,
                    getCache,
                })

                if (fileNode) {
                    node.frontmatter["Hero Image"][i].remoteImage___NODE = fileNode.id
                }
            }
        }
    }
}

Current state

• Due to the fact that Notion API only appeared recently, and it is still in beta, some blocks are marked "unsupported". Among others, images cannot be fetched for now
• Currently, gatsby-source-notion-api can only work with one provided database. In further releases, all databases reachable by the Integration will be available for querying
• Nested blocks are currently skipped. E.g. if a list item has a nested sublist, it's contents will be omitted. This will be fixed in the nearest releases Nested blocks are supported as of 0.4.0!
• Only raw content is available. Raw meaning whatever Notion returns. Further releases will aim at providing a more convenient data format apart from the raw one 0.3.0 features support for archived, createdAt, updatedAt, properties and title.

🎉 You did it
