Description

Dune and Melange default to placing .js artifacts in _build folder. In comparison, ReScript default behavior is to put .js artifacts next to the sources.

To help Melange users look at the resulting .js files, it would be nice to have the ability to "Inspect JavaScript output" from editors. To do so, Dune could look up all the melange.emit stanzas in the workspace and search for the given module emitted in them. Then editor tooling libraries could consume this functionality through rpc.

Research direction

Start by tracing how Dune discovers and processes melange.emit stanzas in a workspace. The work is done when a given Melange source module can be mapped to its emitted JavaScript artifact and the lookup is consumable by editor tooling through RPC.
