Slug Generator

Internally the generator runs every input through the same pipeline before applying a format. It first transliterates non-ASCII characters using a built-in lookup table (TRANSLITERATION_MAP): accented letters fold to their base form (é, ñ, ü become e, n, u), ligatures expand (æ to ae, œ to oe, ß to ss), and common symbols are spelled out rather than dropped, so & becomes 'and', @ becomes 'at', # becomes 'hash', % becomes 'percent', + becomes 'plus', and even Greek letters like α and β become 'alpha' and 'beta'. Turn transliteration off and those same characters are simply removed instead of converted. It then strips anything outside letters, digits, spaces and hyphens with a /[^\w\s-]/g regex, and collapses any run of spaces, underscores or hyphens down to a single separator, which is why double spaces and trailing punctuation never leave stray dashes. The seven formats differ only in the final join: kebab, snake, dot and constant lowercase (or uppercase, for CONSTANT_CASE) and join with -, _ or .; camelCase and PascalCase strip separators entirely and re-case each word boundary.

The stop-word filter checks each word against a built-in list of 88 English function words (a, the, and, of, with, is, how, what, and similar) and drops them before formatting, and the optional max-length cap is separator-aware: rather than slicing mid-word, it backs up to the last hyphen, underscore or dot within the limit so the slug never ends on a partial word (camelCase and PascalCase, having no separators, get a hard character cut). The SEO tab grades the kebab-case result out of 100, subtracting points for concrete problems: 15 points if it exceeds 60 characters, 10 if it carries more than 8 words (it suggests aiming for 3-6), 2 per stop word still present, and 5 each for starting with a digit or choosing a non-kebab format, then it lists the offending stop words and exact issues. Compare mode renders all seven formats for one input at once, batch mode processes one title per line and exports an eight-column CSV (Original plus each format) as slugs-export.csv, a URL preview slots the slug into templates for blog posts, products, API endpoints, file paths or GitHub repos, and your last 20 generated slugs are kept in the browser's local storage under the slugHistory key. Configurations are encoded in the page URL, so a fully set-up generator can be shared with a link.
