If you want to a build custom programming language, the Eclipse ecosystem offers a complete toolstack to build a web-based IDE for it: Theia as the web-IDE framework, Xtext and lsp4j to implement a language server, Sprotty to add diagram support and many more.
In this talk we will show how you can employ Eclipse Theia as application framework and Eclipse Sprotty as graphical framework to create a modeling tool. You will learn about the various considerations that have to be made when designing a user interface for interacting with models, and you will see what Theia and Sprotty are able to contribute in this regard.
Domain-specific languages (DSLs) are a powerful tool to capture arbitrary abstractions of an application domain and map it to code. Eclipse really shines when it comes to integrating DSLs in rich-client workbenches, but how about web-based IDEs?
In this talk you will learn how to bundle the power of four Eclipse frameworks to build a cloud-based IDE with support for your own DSLs:
