Support Raw Loading with `application` and `builder-esbuild`

[mcdenhoed]

Command

build, serve

Description

I have some raw text files that I need to include in my build. To load them with builder-based builds, I am using the webpack raw-loader plugin.

I currently import them as follows:

import contents from "raw-loader!./some-text-file.txt";

It would be amazing if I could do something similar from within the new esbuild-based loader. I saw that vite allows for a ?raw suffix on imports to do just this, but it did not seem to work when I tried it in Angular.

Hopefully I'm just missing something here, but I didn't see this called out in the documentation.

You can actually use import contents from "./some-text-file.txt";

To avoid a TypeScript error, you'll also need to add a type definition file (e.g., src/types.d.ts) with the following:

declare module "*.txt" {
  const content: string;
  export default content;
}

We are also evaluating further customization options for other file types in a future release.

Good to know, thanks! One follow-up question. Should this work for extensions other than .txt? I'm trying to use it on other extensions and am getting a message about no loader being configured for that extension.

[clydin]

Currently just .txt extensions but we are evaluating the inclusion of an additional build option to support configuring other extensions.

That would be a big 👍 from me. My specific use-case is that I'm bundling .frag and .vert WebGL shader sources, and it's nice to keep those with their real extension so that the IDE handles them properly.

This is now in review here: #26371

Awesome, thank you!!

@clydin This doesn't seem to be included in 17.0.2. Any ideas on when we can expect to see this?

[alan-agius4]

This will be available in 17.1.0 which is is currently in prerelease.
