Setup

1. Install spin framework as described on the webpage
2. Make sure that wasm32 targets are added to the toolchain

cd ui
rustup show # check which toolchain is active
# for the active toolchain (1.86.0):
rustup +1.86.0 target add wasm32-unknown-unknown // used for frontend compilation
rustup +1.86.0 target add wasm32-wasip1          // used for backend compilation

Development

set-env SPIN_VARIABLE_KV_EXPLORER_USER demo
set-env SPIN_VARIABLE_KV_EXPLORER_PASSWORD demo
set-env SPIN_VARIABLE_API_TOKEN demo
spin up --build --runtime-config-file runtime_config.toml
curl -X POST -d @api/examples/mixed.json 'http://127.0.0.1:3000/api/v1?token=demo'

Notes:

• Use spin watch to rebuild & run the app on changes.
• Temporarily comment out line with data-wasm-opt="z" in index.html and section [profile.release] in Cargo.toml for faster development cycle.

Deployment

set-env SPIN_VARIABLE_API_TOKEN (tr -dc A-Za-z0-9 </dev/urandom | head -c 16)
spin deploy --build ^
--variable api_token=$E:SPIN_VARIABLE_API_TOKEN ^
--variable kv_explorer_user=$E:SPIN_VARIABLE_KV_EXPLORER_USER ^
--variable kv_explorer_password=$E:SPIN_VARIABLE_KV_EXPLORER_PASSWORD
curl -X POST -d @api/examples/mixed.json 'https://weather.fermyon.app/api/v1?token='$E:SPIN_VARIABLE_API_TOKEN

Notes:

• Temporarily change name of the application in spin.toml if you would like to test before deploying to production.
