Cycle Redundancy Check 32 (CRC32).
Calculates unsigned 32 bit checksum for 0xEDB88320 polynomial.
class CRC32
// Browser and NodeJS compatible.
class CRC32Streams
// Depends on NodeJS "stream" module.
"@tsxper/crc32" package is originally written in TypeScript. TypeScript type definitions are included.
None.
const crc32 = new CRC32();
crc32.calculate('crc32 test');
// or
crc32.forString('crc32 test');
const crc32 = new CRC32();
crc32.forBytes(new TextEncoder().encode('crc32 test'));
Buffer extends Uint8Array.
const crc32 = new CRC32();
crc32.forBuffer(new TextEncoder().encode('crc32 test'));
const crc32 = new CRC32Streams();
const checksum = await crc32.forFile(filePath);
See "Compatibility".
HTML Copy/Paste Example
<!DOCTYPE html>
<html>
<body>
<p>Calculating crc32 for text "hello crc32": <span id="placeholder"></span></p>
<script type="importmap">
{
"imports": {
"@tsxper/crc32": "https://www.unpkg.com/@tsxper/crc32@1.0.5/esm/CRC32.js"
}
}
</script>
<script type="module">
import { CRC32 } from "@tsxper/crc32";
const crc32 = new CRC32();
const crc = crc32.calculate("hello crc32");
document.getElementById('placeholder').innerText = crc;
</script>
</body>
</html>
For example, for sequence of events, converted into Uint8Array[] chunks.
const chunks = [new TextEncoder().encode('text1 text2')];
const crc32 = new CRC32();
let crc = 0;
for (const chunk of chunks) {
crc = crc32.forBytes(chunk, crc);
}
Both, CommonJS and ESM modules are supported.
import { CRC32 } from '@tsxper/crc32';
// or
const { CRC32 } = require('@tsxper/crc32');
Supporting of the both module systems is done through "import", "require" and "default" conditions.
