JavaScript Enum Implementation

A robust enumeration implementation for JavaScript/TypeScript that provides Java-style enums with additional features for TLS 1.3 protocol definitions. @version 0.10.0

Features

• Type-safe enumerations
• Frozen constants to prevent modifications
• Value and name lookups
• Ordinal-based comparison
• JSON serialization
• Built-in TLS 1.3 protocol enumerations

Installation

deno add 'jsr:@tls/enum';

Basic Usage

import{Enum}from'jsr:@tls/enum';classColorextendsEnum{staticRED=newColor('RED','#FF0000');staticGREEN=newColor('GREEN','#00FF00');staticBLUE=newColor('BLUE','#0000FF');static{this.freeze();// Prevent further modifications}}// Usage examplesconsole.log(Color.RED.value);// '#FF0000'console.log(Color.RED.name);// 'RED'console.log(Color.RED.ordinal);// 0console.log(Color.values());// [Color.RED, Color.GREEN, Color.BLUE]console.log(Color.valueOf('GREEN'));// Color.GREENconsole.log(Color.fromValue('#0000FF'));// Color.BLUE

TLS 1.3 Enumerations

SignatureScheme

import{SignatureScheme}from'jsr:@tls/enum';// Access signature schemesconsole.log(SignatureScheme.RSA_PKCS1_SHA256.value);// 0x0401console.log(SignatureScheme.ED25519.name);// 'ED25519'console.log(SignatureScheme.FromValue(0x0403));// 'ECDSA_SECP256R1_SHA256'console.log(SignatureScheme.Values());// [0x0401, 0x0501, ...]

ExtensionType

import{ExtensionType}from'jsr:@tls/enum';// Access extension typesconsole.log(ExtensionType.SERVER_NAME.value);// 0console.log(ExtensionType.SUPPORTED_VERSIONS.name);// 'SUPPORTED_VERSIONS'console.log(ExtensionType.fromValue(43));// ExtensionType.SUPPORTED_VERSIONS

API Reference

Enum Base Class

Static Methods

• size: Get the number of enum constants
• values(): Get all enum constants
• names(): Get all enum constant names
• valueOf(name): Get enum constant by name
• fromValue(value): Get enum constant by value
• freeze(): Prevent further modifications
• isFrozen(): Check if enum is frozen

Instance Properties

• name: The name of the enum constant
• value: The value associated with the enum constant
• ordinal: The position of the constant in the enum

Instance Methods

• toString(): Get string representation
• toJSON(): Get JSON representation
• equals(other): Compare with another enum constant
• compareTo(other): Compare ordinal positions
• [Symbol.toPrimitive](hint): Convert to primitive type

Examples

Creating Custom Enums

classHttpStatusextendsEnum{staticOK=newHttpStatus('OK',200);staticNOT_FOUND=newHttpStatus('NOT_FOUND',404);staticINTERNAL_ERROR=newHttpStatus('INTERNAL_ERROR',500);static{this.freeze();}}// Usageif(response.status===HttpStatus.OK.value){console.log('Request successful');}
