CommonJS modules in script folder: Great idea, can they be used with Dataview?

[Moonbase59]

From an efficiency and code reusability standpoint: Fantastic idea to use a script folder and CommonJS modules.

Some questions:

1. When do they get loaded?

   • Only once on Obsididian startup?
   • Dynamically, i.e. I could add a snippet and it would somehow "see" it?

2. Are all loaded? (So we have to keep the folder small?) Or do they need to be required?

3. Would they work with Dataview JS (inside dataviewjs code blocks)?
   Now that would be something …

Hey @Moonbase59, to answer your questions:

1. They are loaded each time you launch Templater, dynamically. I had some feedback saying it wasn't always reloading when modifying the js file, you can just reload the obsidian app if that's the case
2. All .js files are loaded inside the specified folder.
3. No, you can't access the tp object from the dataviewjs isolated environment. I don't have a good solution for this problem now.

If you feel like it, you can have a look at how js files are loaded in Templater's code here:

Templater/src/UserTemplates/UserTemplateParser.ts

Lines 45 to 66 in b9ca081

	async load_user_script_function(config: RunningConfig, file: TFile): Promise<void> {
	if (!(this.app.vault.adapter instanceof FileSystemAdapter)) {
	throw new TemplaterError("app.vault is not a FileSystemAdapter instance");
	}
	let vault_path = this.app.vault.adapter.getBasePath();
	let file_path = `${vault_path}/${file.path}`;

	if (Object.keys(window.require.cache).contains(file_path)) {
	delete window.require.cache[window.require.resolve(file_path)];
	}
	const user_function = await import(file_path);
	if (!user_function.default) {
	throw new TemplaterError(`Failed to load user script ${file_path}. No exports detected.`);
	}
	if (!(user_function.default instanceof Function)) {
	throw new TemplaterError(`Failed to load user script ${file_path}. Default export is not a function.`);
	}
	this.user_script_functions.set(`${file.basename}`, user_function.default);
	}

Thanks for the info!
