Citation.js converts reference data into CSL-JSON and formats references in styles such as APA and Vancouver. It accepts inputs including BibTeX, BibJSON, DOI, and Wikidata, as well as identifiers such as ISBN, PubMed and PMC IDs, GitHub repository URLs, and npm package URLs. Supported formats include JSON, CSL-JSON, BibLaTeX, RIS, YAML, CFF, and Zenodo Deposit JSON. Identifier resolvers include DOI Content Negotiation, Google Books, OpenLibrary, NCBI’s Literature Citation Explorer, and the Wikidata MediaWiki API. A modular package structure lets users add format and identifier-source plugins as needed; preloaded styles and locales are available for formatted references. Citation.js supports Node.js and browsers, offers a web interface and API, and includes a command-line interface for reading input files, text, or standard input and writing output files or standard output. Example applications include an HTML API wrapper, a Chrome extension for Dutch NWO ISAAC publication data entry, and a BibTeX generator. It is MIT-licensed open-source software, available free.
