The core JavaScript support framework used by NettleWeb projects.
npm install @nettleweb/coreThis library was created for extending the standard JavaScript API while avoiding duplicated dependencies across the modules. It is designed to be fast and lightweight without using dependencies or any platform-specific APIs. It can be safely used in browsers, Node.js or other environments that support the es2022 standard.
npm install @nettleweb/core@latest
Modules
#### Streams
- - alias for Uint8Array but with additional static methods.
- Stream - the base class for ReadStream and WriteStream.
- ReadStream - an abstract readable binary stream.
- WriteStream - an abstract writable binary stream.
- BufferReadStream - a readable stream that uses a Uint8Array as source.
- BufferWriteStream - a writable stream that writes data into a Uint8Array.#### String Coders
-
ASCII
- - useful when TextEncoder and TextDecoder are not available.
- UTF16BE
-
-
- #### Binary Coders
-
- a tool for encoding and decoding Uint8Array into hexadecimal strings.
- Base32 - a tool for encoding and decoding Uint8Array into Base32 strings.
- Base64 - a tool for encoding and decoding Uint8Array into Base64 strings.#### Object Serializers
-
NTON - an object serializer that encodes objects into Uint8Array. (based on the nton npm module)#### Random Number Generators
-
Random - a random number generator interface with multiple algorithm and seeding support.
- SecureRandom - a cryptographically secure random number generator with seeding support.#### Other Utils
-
md5 - generate MD5 checksum from strings.
- cyrb128 - a 128 bit string hashing function.
- AsyncLock - interface for preventing concurrent async executions.
- EventEmitter - a polyfill for the EventEmitter interface in Node.js.Examples
`js
import NettleWeb from "@nettleweb/core";// extract modules for easier access later
const { UTF_8, Base32 } = NettleWeb;
// encode a string into a Uint8Array using utf-8 encoding
const buf = UTF_8.encode("google");
// encode the Uint8Array into a base32 string
const str = Base32.encode(buf);
