🧙‍♀️ Magical regular expressions composer.

It is really easy to mess big regular expressions by forgetting some character. So, instead of using plain strings, @coven/expression provides a set of functions and constants strongly typed, so the type is already a hardcoded string that reflects the regular expression being built, while giving an API that's easier to read and maintain.

Like all Coven Engineering libraries, it has 100% test coverage and it's built in top of modern tech compatible with all JavaScript runtimes.

Example

import { buildUnicode, disjunction, group } from "@coven/expression";

buildUnicode(group(disjunction("this", "that"))); // /(?:this|that)/u
