Please ask for help on the Daml forum if you encounter any issue!

You need to have Node.js and Daml installed.

First, start the Daml components:

daml start

This will:

• Build you Daml code once.
• Generate JavaScript code (and TypeScript definitions) for your Daml types.
• Start a Daml sandbox gRPC server (on 6865).
• Start a Daml HTTP JSON API server (on 7575).
• Watch for the r key press (r + Enter on Windows); when pressed, rebuild all of the Daml code, push the new DAR to the ledger, and rerun the JS/TS code generation.

Next, start the JS dev server:

cd ui
npm install
npm start

This starts a server on http://localhost:3000 which:

• Builds all of your TypeScript (or JavaScript) code (including type definitions from the codegen).
• Serves the result on :3000, redirecting /v1 to the JSON API server (on localhost:7575) so API calls are on the same origin as far as your browser is concerned.
• Watch for changes in TS/JS code (including codegen), and immediately rebuild.

To build everything from scratch:

daml build
daml codegen js .daml/dist/module7-0.1.0.dar -o ui/daml.js
cd ui
npm install
npm run-script build
zip -r ../module7-ui.zip build

Next you need to create a ledger on Daml Hub, upload the files .daml/dist/module7-0.1.0.dar (created by the daml build command) and module7-ui.zip (created by the zip command based on the result of npm run-script build).

Once both files are uploaded, you need to tell Daml Hub to deploy them. A few seconds later, your website should be up and running.
