Leveraging the package.json file for client-side packages, enabling them to be dynamically loaded in the browser

Considering expanding the structure of package.json to incorporate dynamic package (plugin) loading on the client side. I am curious about how this idea aligns with the vision of npm. Essentially, I am interested in loading multiple modules with shared metadata during browser runtime, as opposed to traditional prepackaging methods like npm install -> browserify.

To delve deeper, I am contemplating adding a property such as "myapp-clientRuntimeDependencies" to specify dependencies that will be loaded by the browser rather than through standard prepackaging procedures.

Example package.json:

{
    name: "myapp-package",
    version: "",
    myapp-clientRuntimeDependencies: {
        "myapp-plugin": "file:myapp-plugin",
        "myapp-anotherplugin": "file:myapp-anotherplugin"
    },
    peerDependencies: {
        "myapp-core": "1.0.0"
    }
}

The query: Does this concept conflict with the vision of "npm" and "package.json"? If so, what are the reasons behind it?

I welcome any insights from the npm community.

EDIT:

The initial question may not have been articulated clearly. A better way to phrase it would be:

What is regarded as the most conventional approach (e.g., supported by existing tools, likely endorsed by npm) for defining run-time dependencies between two dynamically loaded front-end packages in package.json?

How can metadata in JSON format be best attached to dynamically loaded front-end packages?

Answer №1

It's not necessarily a direct conflict with the essence of package.json, but it does appear to deviate from its common usage. Normally, package.json is employed before runtime. Incorporating package.json data into your runtime involves loading it in your frontend code. This could pose a problem if you're storing sensitive configurations that shouldn't be exposed via view source.

One aspect that didn't quite mesh for me was your distinction between system.js and jspm being suited for module management while desiring package management. Ultimately, packages and modules are often interchangeable, as a package essentially transforms into a module.

If I'm interpreting your needs correctly, exploring code-splitting might be beneficial...creating distinct js files loaded dynamically based on necessity instead of bundling all javascript into one file. Check out some documentation on how to implement this with webpack here (browserify likely offers similar features).

Answer №2

It seems like your query revolves around incorporating custom app configurations into the package.json file. Your scenario suggests utilizing this configuration to inform your app about which dependencies can be dynamically loaded.

In reality, there are no strict restrictions on adding your own fields to the package.json file, except for the possibility of clashes with reserved names used by npm for other purposes. However, sticking to a unique and specific field name (as demonstrated in your example) should mitigate this risk. In fact, various development tools have already adopted this practice, as highlighted in the post you referenced:

If your tool necessitates metadata for operation, store it in package.json. While customary etiquette would entail seeking permission, we explicitly encourage this approach. Given that the registry is schemaless, any additional field holds equal importance alongside existing ones, steering clear of removal or objections unless conflicting with pre-existing entries.

For an added layer of caution, consider utilizing a separate file (akin to Bower's method) for enhanced safety measures.
