How to set a custom post type in faustjs to find the corresponding page?

[youdianfan]

I custom post address is http://localhost/events/brain-organoids-training-course

When I visit in faustjs and the page returns 404, how do I solve this problem?

Hey. If your page does not resolve to valid template type, you may need to add a custom hook. See the example in Portfolio Blueprint:

https://github.com/wpengine/atlas-blueprint-portfolio/blob/main/plugins/ProjectTemplatePlugin.js

export class EventTemplatePlugin {
  constructor() {}

  apply(hooks) {
    hooks.addFilter('possibleTemplatesList', 'faust', (templates, data) => {
      if (data?.seedNode?.__typename === 'Event') {
        return Array.from(new Set(['event', ...templates]));
      }
      return templates;
    });
  }
}

Behind the scenes Faust uses a seed query to try to find a valid template to use for each page:

https://faustjs.org/docs/faustwp/seed-query

In your example, if the path /events/brain-organoids-training-course returns null for the seedQuery then it won't match any template, so you need to manually add this to the possibleTemplatesList. It all depends on how the CPT was saved using has_archive I think

@theodesp possibleTemplatesList hook doesn't even run for me if the request resolves to 404. So, there's really no opportunity at that time to fix the mismatched SeedQuery (mismatched as in returning null). Is this correct?

I have the same problem. I'm using The Events Calendar which is registering a the post type and link path. I get a 404 and not sure how to get around this.

I had the same issue when I was testing Faust js, I have created a post type products

changes the filename to [[single-product]].js once done restart the localhost

hope this helps

To see the possibleTemplatesList, you need to inspect the server logs in the console. When you visit a CPT page for example and having the above plugin running you should be able to see the info:

info - Possible templates for resolved url: "/events/brain-organoids-training-course": [ 'event', ... ]

This means that the seedQuery was able to resolve the page metadata. Then you need to create a template for the event CPT and export this in the index.js

export default {
  'front-page': frontPage,
  page,
  single,
  event, // <<---- Event template
  archive,
};

If you instead do not see any Possible templates list, then it means that the seedQuery for the /events/brain-organoids-training-course uri resolved to null. This means that in your WordPress site you won't be able to resolve the same uri path.
