How to use this repo

Requirements

• npm
• All commands should be used inside a script project generated with Shopify's App CLI

Installation

npm install -g @shopify/scripts-toolchain-as

Available commands

• shopify-scripts-toolchain-as bootstrap Helper to bootstrap script projects from Shopify's extension points
• shopify-scripts-toolchain-as codegen Helper to code generate MessagePack serializers for EP types in extension points.
• shopify-scripts-toolchain-as build Wrapper around the AssemblyScript compiler. It used to build script projects ensuring compatibility with Shopify's runtime platform.

Usage

Bootstrap

shopify-scripts-toolchain-as bootstrap --from <extension-point-name> --dest <destination dir>

• from the source extension point from where the script project should be bootstrapped
• dest the destination location where the bootstrapped script project is going to be placed

Codegen

shopify-scripts-toolchain-as codegen \
  --interface-definition=EP/interface.ts \
  -- --lib=./node_modules --optimize --use Date=

Build

shopify-scripts-toolchain-as build \
  --src ./myscript.ts \
  --binary ./myscript.wasm \
  --metadata ./metadata.json

• src the name and location of the script's entrypoint
• binary the name and the location to place the generated WebAssembly binary
• metadata the name and location to place the generated script's metadata

Since this tool is a wrapper around the AssemblyScript's compiler, additional commands can be passed down to the AssemblyScript compiler CLI

npx shopify-scripts-toolchain-as build \
  --src=sample/script.ts \
  --binary=sample/build.wasm \
  --metadata ./metadata.json \
  -- --lib=node_modules --lib=sample --validate --optimize
