deka

deka is a programming language and runtime for building reliable web applications. It compiles to JavaScript and runs both natively and in the browser via WASM.

Getting started

Build the CLI:

cargo build --release -p cli

Run the language suite:

./run.sh

Native runtime validation runs with ./run.sh against local workspace crates. App testing remains available through deka test. See TESTING.md.

Local package development

Link a package working tree into a consumer without changing deka.json or deka.lock:

deka link ../my-package
deka unlink @scope/my-package

Links are stored in the consumer's developer-only .deka/links.json (keep .deka/ out of version control). During bundling, a local link takes precedence over the installed copy in ds_modules; deka unlink removes only that metadata and never deletes the package working tree. The linked package must declare a scoped name such as @scope/my-package in its deka.json.
