Notum, a Strapi implementation partner from the Czech Republic, has developed three open-source plugins to enhance the functionality of the Strapi content management system: content versioning, record locking, and location filtering. The content versioning plugin, which is popular with nearly 10,000 monthly downloads, allows for multiple draft versions of content and integrates with Strapi's internationalization features, although it lacks support for unique fields within components. The record-locking plugin prevents data loss by indicating when content is being edited by another user, utilizing web sockets to manage editing status. The location plugin, which uses the PostGIS extension for geospatial queries, allows users to filter content based on geographical data and has quickly gained popularity. The plugins demonstrate Notum's commitment to the Strapi community and the potential of open-source collaboration to address specific use cases that Strapi's core features may not cover, with the company actively maintaining and updating these tools based on user feedback.
