@hdml/hash is a lightweight utility library designed for hashing and generating unique identifiers. It provides various functions to handle hashing and timestamp-related operations, making it ideal for applications that require unique and consistent identifiers or time-based hashing. This module is part of the HDML-Utilities monorepo, which aims to provide tools for working with hierarchical data structures in web-based environments.
- MD5 Hashing: Compute MD5 hash values for strings.
- UUID Generation: Generate session-unique UUID-like strings.
- Hashify: Convert content to a unique hash name using a specific charset.
- Hashed Timestamp: Generate a consistent hash for a timestamp based on a timestep value.
- Parse Time Hash: Retrieve the timestamp from a hashed time string.
To install @hdml/hash, use npm:
npm install @hdml/hashmd5(content: string): string
Generates an MD5 hash from the provided string.
uid(): string
Generates a session-unique UUID-like string.
hashify(content: string): string
Converts a string to a unique hash name using a custom charset based on its MD5 value.
hashtime(timestamp: number, timestep: number = 1): string
Returns a persistent hash for the provided timestamp rounded by the given timestep (in milliseconds). The hash is represented in base-36 format.
parsetime(hashtime: string, timestep: number = 1): number
Converts the base-36 hashtime string back to its original timestamp using the provided timestep.
