Building and developing
You only need to run install the dependencies once in the repository root by
yarn install. This will install all dependencies and link them in each
node_modules. You should not run
yarn install in each
project's directory separately.
This will also link the
dist folder from the web project as
dolos-web in the
CLI project as long as the
dolos-web with the
correct version as a dependency. This allows you to simultaneously develop the
CLI and the Web project together.
Each project has its own build instructions in its own directory.
