Context:
I am trying to add svelte to our application, which has previously been using
tsc
to typecheck our codebase, (andesbuild
to build).tsc
andsvelte-check
were both annoying when run from a process manager, such as overmind, which runs multiple cli tools/watchers etc in the same terminal. This is because they by default clear the screen periodically, which blows away useful information from other tools.tsc
supports--preserveWatchOutput
, (link) so I added the same flag to svelte-check.
