Description

The core functionality for fsx that is shared across all implementations for all runtimes. The contents of this package are intentionally runtime agnostic and are not intended to be used alone.

Currently, this package simply exports the Fsx class, which is an abstract base class intended to be inherited from in runtime-specific fsx packages (like fsx-node).

[!WARNING] This project is experimental and may change significantly before v1.0.0. Use at your own caution and definitely not in production!

Installation

Node.js

Install using your favorite package manager for Node.js:

npm install fsx-core

# or

pnpm install fsx-core

# or

yarn add fsx-core

# or

bun install fsx-core

Then you can import the Fsx class like this:

import { Fsx } from "fsx-core";

Deno

For Deno, set up a deno.json file like this:

{
	"imports": {
		"fsx-core": "npm:fsx-core@latest"
	}
}

Then you can import the Fsx class like this:

import { Fsx } from "fsx-core";

Browser

It's recommended to import the minified version to save bandwidth:

import { Fsx } from "https://cdn.skypack.dev/fsx-core?min";

However, you can also import the unminified version for debugging purposes:

import { Fsx } from "https://cdn.skypack.dev/fsx-core";

Usage

The Fsx class contains all of the basic functionality for an Fsx instance without a predefined impl. This class is mostly used for creating runtime-specific impls, such as NodeFsx and DenoFsx.

You can create your own instance by providing an impl directly:

const fsx = new Fsx({ impl: { async text() {} }});

The specified impl becomes the base impl for the instance, meaning you can always reset back to it using resetImpl().

You can also inherit from Fsx to create your own class with a preconfigured impl, such as:

class MyFsx extends Fsx {
	constructor() {
		super({
			impl: myImpl
		});
	}
}
