Example usage of all Fermyon KV functions

Example of Every Single Spin KV Function in TypeScript

This is a TypeScript app that shows an example of every single one of the KV function that Fermyon Spin and Fermyon Cloud support.

Head to src/index.ts to see the examples, and spin.toml to see the config.

Running the examples

If you have Spin installed, you can clone this repo, and do the following to get it up and running:

$ npm init    # Install the packages
$ spin build  # Run locally
$ spin up     # Test locally
$ curl localhost:3000
$ spin deploy # Test on Fermyon Cloud
$ curl https://all-kv-functions-XXXXXX.fermyon.app # where XXXXXX is whatever code Fermyon generates for you

Expected Output

The HTTP handler will return a boring response instructing you to check your logs:

$ curl localhost:3000/
Check your logs for the results of this

Your logs will show the details of the operations:

The keys in the DB are: name, pets
Site name: Pet Database
Got an expected 'null' for a nonexistent key
The second pet is named Julius
When using get() on JSON: [{"name":"Tiberius","type":"dog"},{"name":"Julius","type":"cat"},{"name":"Toez","type":"cat"}]
Error opening non-existent DB: InternalError: Error::AccessDenied
Error parsing non-JSON as if it were JSON: SyntaxError: unexpected token: 'Pet'
Replaced Pet Database with My Pets

Using Spin locally, these will go to STDOUT. Using Fermyon Cloud, you can view this in the app's console in the web interface.
