Dynamic import at compile time

I am trying to import files dynamically based on a glob pattern. These files are not imported correctly when I compile the application. It only works with a static string. Is there any way to make it work with the glob pattern? or is there a workaround? Or do I just have to import the files using static strings

Can you show some example code you're trying to run?

import { existsSync, expandGlob } from '@std/fs';

/**
* Dynamically import all files matching the glob pattern
* @param globPath The glob pattern to match files
*/
export async function importer(globPath: string) {
for await (const file of expandGlob(globPath)) {
if (file.isFile) {
await import(`file://${file.path}`);
}
}
}
import { existsSync, expandGlob } from '@std/fs';

/**
* Dynamically import all files matching the glob pattern
* @param globPath The glob pattern to match files
*/
export async function importer(globPath: string) {
for await (const file of expandGlob(globPath)) {
if (file.isFile) {
await import(`file://${file.path}`);
}
}
}
This is the code I am using to import the files. The importer function gets called in the entrypoint the project

That looks correct and the way to do it. What's the exact problem you're running into? If you want to use it with deno compile you can use --include flag to include files into the compiled binary to be later dynamically imported

Wow I completely forgot to include the --include flag. That should do it, will test it when I'm back on my pc. Thank you! hm, I've tried the following --include ./src/modules/**/*.ts but it still isn't included. Any other suggestions?

Try wrapping this in a quotes - otherwise it will be your shell that expands the glob If it doesn't work I'd appreciate an issue - maybe you will need to specify --include flag multiple times once for each file Which seems bad and we should fix it

I have tried specifying each file separately but it still doesn't work. I have opened an issue. If it needs more clarification please let me know

The issue is closed as wont fix as it is basically impossible to implement which is fair. but then I might need some help with the include flag. I have used it like this --include "./src/modules/core/baseEvents.ts" is this the correct way to do this? And how will this work code wise? I'm just trying to get all the information needed to make it work ๐Ÿ˜…

Yeah that's correct way to do it Eg if you are in ./src/main.ts file you can import that included file as await import(import.meta.resolve("./modules/core/baseEvents.ts")

This looks very promising! Will definitely check it out. I finished my compile script yesterday :cookie_deno: Thank you (again ๐Ÿ˜‰)
