[crookse]

Closes #622

TODO

• Documentation

  • Resource Loader pages
    • PR: feat(drash/v2.x): ResourceLoaderService docs website-v2#171
    • Page: https://drash-land-git-feat-resource-loader-service-drash-land.vercel.app/drash/v2.x/tutorials/services/drash-approved-services/resource-loader
• Integration Tests

Summary

• feat: adds ResourceLoaderService
• feat: drash_resource property to Drash.Resource to help identify extended resources as a Drash.Resource
• refactor: resources service config optional since they can be loaded via the ResourceLoaderService

Example Usage

If the folder structure looks like:

/path/to/project
  |-- /api_resources
  |    |-- orders_resource.ts
  |    |-- users_resource.ts
  |
  |-- /ssr_resources
  |    |-- home_page_resource.ts
  |    |-- contact_page_resource.ts
  |
  |-- app.ts
  |-- deps.ts

import { Drash, ResourceLoaderService } from "./deps.ts";

const resourceLoaderService = new ResourceLoaderService({
  paths_to_resources: [
    "./api_resources", // <--- Loads orders_resource and users_resource
    "./ssr_resources", // <--- Loads home_page_resource and contact_page_resource
  ],
});

const server = new Drash.Server({
  hostname: "localhost",
  port: 1447,
  protocol: "http",
  services: [resourceLoaderService],
});

server.run();

console.log(`Server running at ${server.address}.`);

@Guergeiro @ebebbington , not sure what's going on with the windows test with trying to dynamically import

d:\a\drash\drash\tests\integration\services\resource_loader\resources\api\users_resource.ts

is that a thing on windows? lol. no rush on this. check when you're free.

[ebebbington]

@crookse maybe use a combo of, or one of: new URL or import.meta.main?

[Guergeiro]

Here's the problem Windows paths don't work like that. I would advise using join.
