just scripts

#!/bin/bash
set -e

build:x()(
    true "${NODE:?}"
    for target in \
        x86_64-pc-windows-msvc \
        aarch64-unknown-linux-gnu \
        x86_64-unknown-linux-gnu \
        aarch64-apple-darwin \
        x86_64-apple-darwin \

        cargo build --target "$target" "$@"
    done
)

cd "$(dirname "${BASH_SOURCE[0]}")"; c=$1; shift; "$c" "$@"

This example uses a ./just <script>-style runner. Why? So that all the scripts can be contained in a single Bash just file. It runs on Windows too using either Git Bash or WSL.

What's going on there? Let's break it down:

• "build": "<build-own-target>": This should build only for your local target. Think like cargo build or go build. For local development.

• "postbuild": "0oscpu build me && 0oscpu link me": Builds the out/$OS-$ARCH/ package folder and npm link-s it to the current workspace.

• "build:x": "<build-all-targets>": This should build all the targets. Usually this is something like bash ./build-all-targets.sh. Should be run before npm publish to build everything.

• "postbuild:x": "0oscpu build": Builds the out/$OS-$ARCH/ package folders for every key in the package.json's 0oscpu map. Should be run before npm publish.

• "optionalDependencies": { ... }: This is the magic. We are mapping custom names (@me/$OS-$ARCH by convention) to the magic prerelease versions.
