Shortid
shortid is a library for creating compact, non-sequential strings used as unique identifiers for database records and public URLs. It functions as a URL-friendly identifier utility designed to produce short alphanumeric strings.
The project allows for the use of a custom alphabet to control the visual appearance of identifiers and avoid ambiguity. This custom character set mapping ensures that generated keys meet specific formatting or branding requirements.
The system includes capabilities for non-sequential key generation to prevent resource enumeration, as well as tools to validate whether a given string adheres to the expected identifier format and character set.
Features
- Unique Identifier Generators - Provides a utility for creating compact, non-sequential, and URL-friendly unique identifiers.
- Unique Identifier Generators - Provides a library for generating compact, non-sequential strings used as unique identifiers for database records and URLs.
- Non-Sequential Generators - Produces unpredictable identifiers to prevent security risks associated with sequential numbering.
- Non-Sequential Identifier Generators - Implements a mechanism for generating unpredictable unique identifiers to prevent resource enumeration.
- Custom Character Set Definitions - Provides the ability to specify the exact set of characters used to build identifiers for specific requirements.
- Custom Alphabet Encodings - Implements a custom alphabet encoding to map values into compact, URL-friendly string representations.
- Custom Character Sets - Allows the use of a user-defined string of characters to control the visual appearance and safety of IDs.
- Identifier Formatters - Produces unique identifiers using specific character sets to meet strict branding or technical requirements.
- URL Identifiers - Generates compact, URL-safe alphanumeric identifiers specifically formatted for use in web addresses and link shorteners.
- Short Key Generators - Generates short and unique keys for MongoDB or Redis records to replace predictable default identifiers.
- Deterministic Symbol Selection - Uses a random number generator to predictably select characters from a predefined array.
- Selection Randomization - Prevents identifier predictability by shuffling character selection through random number generation.
