+
+In-memory file-system with [Node's `fs` API](https://nodejs.org/api/fs.html).
+
+- Node's `fs` API implemented, see [_old API Status_](./docs/api-status.md), [missing list](https://github.com/streamich/memfs/issues/735), [missing `opendir`](https://github.com/streamich/memfs/issues/663)
+- Stores files in memory, in `Buffer`s
+- Throws sameish\* errors as Node.js
+- Has concept of _i-nodes_
+- Implements _hard links_
+- Implements _soft links_ (aka symlinks, symbolic links)
+- Permissions may\* be implemented in the future
+- Can be used in browser, see [`memfs-webpack`](https://github.com/streamich/memfs-webpack)
+
+### Install
+
+```shell
+npm install --save memfs
+```
+
+## Usage
+
+```js
+import { fs } from 'memfs';
+
+fs.writeFileSync('/hello.txt', 'World!');
+fs.readFileSync('/hello.txt', 'utf8'); // World!
+```
+
+Create a file system from a plain JSON:
+
+```js
+import { fs, vol } from 'memfs';
+
+const json = {
+  './README.md': '1',
+  './src/index.js': '2',
+  './node_modules/debug/index.js': '3',
+};
+vol.fromJSON(json, '/app');
+
+fs.readFileSync('/app/README.md', 'utf8'); // 1
+vol.readFileSync('/app/src/index.js', 'utf8'); // 2
+```
+
+Export to JSON:
+
+```js
+vol.writeFileSync('/script.sh', 'sudo rm -rf *');
+vol.toJSON(); // {"/script.sh": "sudo rm -rf *"}
+```
+
+Use it for testing:
+
+```js
+vol.writeFileSync('/foo', 'bar');
+expect(vol.toJSON()).toEqual({ '/foo': 'bar' });
+```
+
+Create as many filesystem volumes as you need:
+
+```js
+import { Volume } from 'memfs';
+
+const vol = Volume.fromJSON({ '/foo': 'bar' });
+vol.readFileSync('/foo'); // bar
+
+const vol2 = Volume.fromJSON({ '/foo': 'bar 2' });
+vol2.readFileSync('/foo'); // bar 2
+```
+
+Use `memfs` together with [`unionfs`][unionfs] to create one filesystem
+from your in-memory volumes and the real disk filesystem:
+
+```js
+import * as fs from 'fs';
+import { ufs } from 'unionfs';
+
+ufs.use(fs).use(vol);
+
+ufs.readFileSync('/foo'); // bar
+```
+
+Use [`fs-monkey`][fs-monkey] to monkey-patch Node's `require` function:
+
+```js
+import { patchRequire } from 'fs-monkey';
+
+vol.writeFileSync('/index.js', 'console.log("hi world")');
+patchRequire(vol);
+require('/index'); // hi world
+```
