Creating a new project

Pre requisites

• NodeJS 16
• Rust 1.61.0-nightly (c5cf08d37 2022-03-30)

Create project

You can create a new project by running the following lines:

npm init
npm install --save-dev assemblyscript
npx asinit .

In order to clean some unnecessary files and code, please apply following changes to the project:

• Remove tests folder
• Remove index.html
• Remove code in assembly/index.ts
• Remove all scripts in package.json

Add these entries in scripts field on package.json:

{
  "scripts":{
    "asbuild:release": "asc assembly/index.ts --target release --bindings esm --use abort= --transform  @zondax/fvm-as-bindgen",
    "asbuild": "npm run asbuild:release"
  }
}

Finally, create a Makefile at project root folder, and paste this content:

deps:
    yarn install
    cargo install wizer --all-features --force

build:
    yarn asbuild
    wizer build/release.wasm -f init -o build/release.wasm

.PHONY: deps build

Install deps

Now it is time to add dependencies

yarn add @zondax/fvm-as-sdk
yarn add @zondax/fvm-as-bindgen
yarn add @zondax/assemblyscript-cbor

Finally, install them running

make deps
