+# peek-readable
+
+A promise based asynchronous stream reader, which makes reading from a stream easy.
+
+Allows to read and peek from a [Readable Stream](https://nodejs.org/api/stream.html#stream_readable_streams) 
+
+Note that [peek-readable](https://github.com/Borewit/peek-readable) was formally released as [then-read-stream](https://github.com/Borewit/peek-readable).
+
+## Usage
+
+### Installation
+
+```shell script
+npm install --save peek-readable
+```
+
+The `peek-readable` contains one class: `StreamReader`, which reads from a [stream.Readable](https://nodejs.org/api/stream.html#stream_class_stream_readable).
+
+### Compatibility
+
+Module: version 5 migrated from [CommonJS](https://en.wikipedia.org/wiki/CommonJS) to [pure ECMAScript Module (ESM)](https://gist.github.com/sindresorhus/a39789f98801d908bbc7ff3ecc99d99c).
+JavaScript is compliant with [ECMAScript 2019 (ES10)](https://en.wikipedia.org/wiki/ECMAScript#10th_Edition_%E2%80%93_ECMAScript_2019).
+Requires Node.js ≥ 14.16 engine.
+
+## Examples
+
+In the following example we read the first 16 bytes from a stream and store them in our buffer.
+Source code of examples can be found [here](test/examples.ts).
+
+```js
+import fs from 'node:fs';
+import { StreamReader } from 'peek-readable';
+
+(async () => {
+  const readable = fs.createReadStream('JPEG_example_JPG_RIP_001.jpg');
+  const streamReader = new StreamReader(readable);
+  const uint8Array = new Uint8Array(16);
+  const bytesRead = await streamReader.read(uint8Array, 0, 16);;
+  // buffer contains 16 bytes, if the end-of-stream has not been reached
+})();
+```
+
+End-of-stream detection:
+```js
+(async () => {
+
+  const fileReadStream = fs.createReadStream('JPEG_example_JPG_RIP_001.jpg');
+  const streamReader = new StreamReader(fileReadStream);
+  const buffer = Buffer.alloc(16); // or use: new Uint8Array(16);
+
+  try {
+    await streamReader.read(buffer, 0, 16);
+    // buffer contains 16 bytes, if the end-of-stream has not been reached
+  } catch(error) {
+    if (error instanceof EndOfStreamError) {
+      console.log('End-of-stream reached');
+    }
+  }
+})();
+```
+
+With peek you can read ahead:
+```js
+import fs from 'node:fs';
+import { StreamReader } from 'peek-readable';
+
+const fileReadStream = fs.createReadStream('JPEG_example_JPG_RIP_001.jpg');
+const streamReader = new StreamReader(fileReadStream);
+const buffer = Buffer.alloc(20);
+
+(async () => {
+  let bytesRead = await streamReader.peek(buffer, 0, 3);
+  if (bytesRead === 3 && buffer[0] === 0xFF && buffer[1] === 0xD8 && buffer[2] === 0xFF) {
+    console.log('This is a JPEG file');
+  } else {
+    throw Error('Expected a JPEG file');
+  }
+
+  bytesRead = await streamReader.read(buffer, 0, 20); // Read JPEG header
+  if (bytesRead === 20) {
+    console.log('Got the JPEG header');
+  } else {
+    throw Error('Failed to read JPEG header');
+  }
+})();
+```
