## Description
|
|
|
|
The `hfs` bindings for use in Node.js and Node.js-compatible runtimes.
|
|
|
|
> [!WARNING]
|
|
> This project is **experimental** and may change significantly before v1.0.0. Use at your own caution and definitely not in production!
|
|
|
|
## Installation
|
|
|
|
Install using your favorite package manager:
|
|
|
|
```shell
|
|
npm install @humanfs/node
|
|
|
|
# or
|
|
|
|
pnpm install @humanfs/node
|
|
|
|
# or
|
|
|
|
yarn add @humanfs/node
|
|
|
|
# or
|
|
|
|
bun install @humanfs/node
|
|
```
|
|
|
|
## Usage
|
|
|
|
The easiest way to use hfs in your project is to import the `hfs` object:
|
|
|
|
```js
|
|
import { hfs } from "@humanfs/node";
|
|
```
|
|
|
|
Then, you can use the API methods:
|
|
|
|
```js
|
|
// 1. Files
|
|
|
|
// read from a text file
|
|
const text = await hfs.text("file.txt");
|
|
|
|
// read from a JSON file
|
|
const json = await hfs.json("file.json");
|
|
|
|
// read raw bytes from a text file
|
|
const arrayBuffer = await hfs.arrayBuffer("file.txt");
|
|
|
|
// write text to a file
|
|
await hfs.write("file.txt", "Hello world!");
|
|
|
|
// write bytes to a file
|
|
await hfs.write("file.txt", new TextEncoder().encode("Hello world!"));
|
|
|
|
// append text to a file
|
|
await hfs.append("file.txt", "Hello world!");
|
|
|
|
// append bytes to a file
|
|
await hfs.append("file.txt", new TextEncoder().encode("Hello world!"));
|
|
|
|
// does the file exist?
|
|
const found = await hfs.isFile("file.txt");
|
|
|
|
// how big is the file?
|
|
const size = await hfs.size("file.txt");
|
|
|
|
// when was the file modified?
|
|
const mtime = await hfs.lastModified("file.txt");
|
|
|
|
// copy a file from one location to another
|
|
await hfs.copy("file.txt", "file-copy.txt");
|
|
|
|
// move a file from one location to another
|
|
await hfs.move("file.txt", "renamed.txt");
|
|
|
|
// delete a file
|
|
await hfs.delete("file.txt");
|
|
|
|
// 2. Directories
|
|
|
|
// create a directory
|
|
await hfs.createDirectory("dir");
|
|
|
|
// create a directory recursively
|
|
await hfs.createDirectory("dir/subdir");
|
|
|
|
// does the directory exist?
|
|
const dirFound = await hfs.isDirectory("dir");
|
|
|
|
// copy the entire directory
|
|
hfs.copyAll("from-dir", "to-dir");
|
|
|
|
// move the entire directory
|
|
hfs.moveAll("from-dir", "to-dir");
|
|
|
|
// delete a directory
|
|
await hfs.delete("dir");
|
|
|
|
// delete a non-empty directory
|
|
await hfs.deleteAll("dir");
|
|
```
|
|
|
|
If you'd like to create your own instance, import the `NodeHfs` constructor:
|
|
|
|
```js
|
|
import { NodeHfs } from "@humanfs/node";
|
|
import fsp from "fs/promises";
|
|
|
|
const hfs = new NodeHfs();
|
|
|
|
// optionally specify the fs/promises object to use
|
|
const hfs = new NodeHfs({ fsp });
|
|
```
|
|
|
|
If you'd like to use just the impl, import the `NodeHfsImpl` constructor:
|
|
|
|
```js
|
|
import { NodeHfsImpl } from "@humanfs/node";
|
|
import fsp from "fs/promises";
|
|
|
|
const hfs = new NodeHfsImpl();
|
|
|
|
// optionally specify the fs/promises object to use
|
|
const hfs = new NodeHfsImpl({ fsp });
|
|
```
|
|
|
|
## Errors Handled
|
|
|
|
* `ENOENT` - in most cases, these errors are handled silently.
|
|
* `ENFILE` and `EMFILE` - calls that result in these errors are retried for up to 60 seconds before giving up for good.
