Create components using a plugin

Hi all,
I’m wondering how create components “programmatically” using a plugin. After googling and searching in this forum seems impossibile.
But… how do the magic like strapi-plugin-seo (@Mcastres ) that add components in a strapi instance?
Maybe it’s necessary to create a components and then create a routine to add them to the UI?
Thanks

Hello Vito :wave:

I’m trying to understand your question. What happens in the SEO plugin is that I created two “static” components and in the server part of the plugin I use the content-type-builder plugin components API to create a component directly which, contains a sub-component :slight_smile:

For the SEO plugin use case, the components are statics. But you can make it dynamic of course depending on what you receive from the front-end for example.

Happy to answer any other questions!

Oh, sorry, you right.
I forgot to explain my scenario.

I want to create a plugin with a content-type and two different components.

The content-type is OK, but the components created in the folder /server/components/mycomponents/XX.json are “invisible” in the strapi instance, only the content-type is listed.
And more: if I add a field component-type to the json schema of the content, I obtain an error when strapi tries to start:

[2022-09-13 12:45:38.500] debug: ⛔️ Server wasn't able to start properly.
[2022-09-13 12:45:38.501] error: Cannot read properties of undefined (reading 'attributes')

Ok, I read the source code of the seo-plugin, and now is more clear for me.
So, my question could be:
can I use the lifecycle of Strapi to add automatically a specific component to a specific content-type?

@vito80ba I have the same issue.
/server/components/mycomponents/XX.json is “invisible” in the strapi instance.
It only works when I add the component inside: src/components/XX.json.

Did you find a way to solve this issue?

Kind regards,
Seppe

I don’t know if something has changed in this year (and what is your scenario), but when I worked for this task I discovered that when you want to create programmatically content-types and components (ex. with a custom plugin) you could create only content-types, than you’ve to set a script in the UI that link content-types with your components.

Hi! I’m indeed working on a custom plugin. We created a content type which we want to combine with components. In this case we would like to add multiple color cards (components) in our content-type “styleguide”. Seems like it’s only possible with a custom script indeed… ugh

Schema content-type Styleguide

  "kind": "singleType",
