Local Functions Development

The following instructions are for building and testing Function templates, which follow the pattern functions-*-[rs|js].

Expand Liquid Templates

If you wish to build and test the functions templates, you must first expand any .liquid templates with the following command.

yarn
yarn expand-liquid [rust|vanilla-js|typescript] <project-name-without-suffix>
# example: yarn expand-liquid rust functions-cart-checkout-validation

# optionally specify only the language argument to expand all functions projects for that language
yarn expand-liquid rust
yarn expand-liquid typescript
yarn expand-liquid vanilla-js
yarn expand-liquid wasm

yarn
# Generate types from GraphQL schemas
