# Cache the dependencies as a layer (the following two steps are re-run only when deno.json/deno.lock is modified).
# Install dependencies from npm and JSR registries instead of copying deps folder

RUN rm deno.lock && \
  deno install

# These steps will be re-run upon any file change in your working directory:
ADD src /app/src
