# Makes `--target wasm32-mvp` resolve to linera-service/wasm32-mvp.json

Rather than using wasm32-mvp, let's add two targets that we can distinguish:

  • wasm32-linera-chain for on-chain applications (contract and service)
  • wasm32-unknown-js-web for the Web browser (@linera/client)

Then we can throw away the web features that are currently polluting our codebase.

(I'll suggest one target for both contract and service, even though it might be cleaner to separate them, because it eases compilation of applications for the end-user)
