Build a Role-Based LMS with In-Document Learning Using a React PDF Viewer

A step-by-step guide to building a role-based Learning Management System (LMS) assignment workflow in React using the Syncfusion React PDF Viewer. The workflow covers the full assignment lifecycle: staff uploading learning materials and fillable PDFs, learners reviewing content and submitting answers in-browser, automated scoring via form field extraction, in-document annotations and comments for Q&A, and retest handling — all without file downloads or external tools. Key implementation details include role-based toolbar configuration, the exportFormFieldsAsObject API for autoscoring, and a status state machine (New → In-Progress → Completed/Retest).
