PureScript examples #

Runnable examples for this personal, unofficial experimental SDK, targeting Dagger 1.0.0-beta.21.

Example	What it demonstrates
Container pipeline	Connect to Dagger, execute a container, and read its output
Dagger module	Expose a greeting and a function returning a Dagger container

Run the pipeline #

From the repository root, install the pinned CLI first:

mise trust
mise install

Install Node.js 22 or newer. The pipeline builds in the SDK workspace, using its pinned Spago and PureScript versions. Docker or another configured Dagger engine must be available.

Starting from the repository root:

cd purescript
npm install
npx spago build --purs-args "examples/pipeline/src/**/*.purs"
mise exec -- dagger api with-session -- node examples/pipeline/run.mjs

Expected output: Hello from PureScript! (Dagger may also print progress).

Run the module #

The module example contains the source you own. Let the SDK scaffold the package and generate its engine-specific dependency in a separate workspace. This keeps generated files out of the example source directory.

From the repository root:

export SDK_REPO="$PWD"
export DAGGER="$(mise which dagger)"
mkdir -p ../hello-purescript-workspace
cd ../hello-purescript-workspace
git init
"$DAGGER" init
"$DAGGER" module install "$SDK_REPO/purescript" --name purescript
"$DAGGER" module init purescript --name hello-purescript --path ./hello-purescript -y
cd hello-purescript
cp "$SDK_REPO/purescript/examples/module/src/Main.purs" src/Main.purs
"$DAGGER" generate -y
"$DAGGER" api call -m . hello --name developer
"$DAGGER" api call -m . container --message "Hello from a module!" stdout

The greeting returns Hello, developer!. The second call returns a lazy container and then requests its stdout, producing Hello from a module!. Keep the generated SDK and module configuration with your module project.

See the SDK guide for API details and tests.
