Development

Before start, copy wrangler.toml.example and name it wrangler.toml. This file will be used to configure the development environment and define all the environment variables that you need for your application.

cp wrangler.toml.example wrangler.toml

To starts the vite dev server:

npm run dev

You can also start the Playwright UI mode to test your application. You will find all the tests defined in the /tests/e2e directory.

npm run test

To test your application on the workerd runtime, you can start the wrangler dev server with:

npm run build && npm run start

New environment variable

To add a new environment variable, you can update the var section on the wrangler.toml file with the new variable:

[vars]
NEW_VARIABLE = "..."

The variable will be available from the env object in the context.

Setup a KV Namespace

To setup a new KV namespace on the development environment, update wrangler.toml with another object similar to the cache namespace as shown below:

kv_namespaces = [
  { binding = "cache", id = "cache" },
  { binding = "new_namespace", id = "new_namespace" }
]

Note that the id has no effect on the dev environment. You can use the same name for both id and binding. The namespace will be available form the env object in the context.

Improving types
