I made a plugin, not for Discourse but for Gatsby. The plugin sources topic lists from a Discourse installation and transforms into Gatsby nodes. It simplifies using Discourse a headless CMS.
We use it in a project to build a microblog and a calendar that auto updates when new content is added to the forum.
Here is the microblog:
Source: https://foodshift.se/t/forenade-inkop-nyheter-blogg/290/9
Result: https://forenadeinkop.se/blogg
And, here is the calendar:
Source: https://foodshift.se/tags/c/events/13/forenade-inkop/l/agenda
Result: https://forenadeinkop.se (at the bottom)
Hope someone else finds it useful!
gatsby-source-discourse-topic-list helps you source topic lists from the Discourse discussion forum platform and transform it into Gatsby nodes.
In addition to the topic list provided by the Discourse api, the plugin also fetches the raw text for each topic.
Getting Started
- Install the package with yarn or npm
yarn add gatsby-source-discourse-topic-list
- Add to plugins in your gatsby-config.js
module.exports = {
plugins: [
{
resolve: "gatsby-source-discourse-topic-list",
options: {
url: "https://my-discourse-server.com"
endPoint: 'top.json',
}
}
]
};
Options
| Name | Type | Description |
|---|---|---|
| url | object or string | Required. Url of your Discourse installation as a string. If you have two different APIs for development and production, define an object with the keys production and development. |
| endPoint | string | Required. Any Discourse API endpoint returning a topic_list. |
| rootKey | string | Optional. Name your API. |
Example Discourse API endpoints
Latest topics in a category:
options: {
url: "https://meta.discourse.org"
endPoint: 'c/1.json',
}
Latest topics in a category, filtered by tag:
options: {
url: "https://meta.discourse.org"
endPoint: 'tags/c/bug/1/pr-welcome.json',
}
Top topics in a category:
options: {
url: "https://meta.discourse.org"
endPoint: 'c/support/6/l/top.json',
}
See the Discourse API documentation for a full list of endpoints.
Example result
Note the added raw field containing the full unprocessed post topic text.
{
"users": [
{
"id": 0,
"username": "string",
"avatar_template": "string"
}
],
"topic_list": {
"can_create_topic": true,
"draft": {},
"draft_key": "string",
"draft_sequence": 0,
"for_period": "string",
"per_page": 0,
"topics": [
{
"id": 0,
"title": "string",
"fancy_title": "string",
"slug": "string",
"raw": "The full unprocessed topic text in markdown format",
...
}
]
}
}
Multiple Sources? Multiple Instances!
If you would like to fetch multiple endpoints in your project, just instantiate the plugin multiple times. Just be sure to set a different rootKey for every instance.
