Back-end DeveloperContributions:34 commits in 1 year 3 months
Contributions summary:Jordan primarily contributed to the back-end functionality of Etherpad Lite, implementing features for the HTTP API. This involved adding POST request handling, session management through a 'requireSession' mode, and an 'editOnly' option to control pad creation. Furthermore, the user's work included sanitizing pad names and enhancing the export functionality with specific pad revision exports. These changes suggest a focus on API design, access control, and user interaction within the document editor.
