This guide covers the build process for SubWallet Extension, including available build scripts, output locations, and production builds.

​
Prerequisites

Before building the extension, ensure you have:
  • Node.js (v14 or later)
  • Yarn 3.0.1 or later
  • All dependencies installed via yarn install

​
Build Process

SubWallet Extension uses a multi-step build process that compiles TypeScript, bundles assets, and creates distribution packages.

​
Development Build

1

Build TypeScript

The first step compiles all TypeScript files in the monorepo:
yarn koni-dev-build-ts
This script processes all packages referenced in tsconfig.json:
  • extension-base
  • extension-chains
  • extension-compat-metamask
  • extension-dapp
  • extension-inject
  • extension-mocks
  • extension-koni
  • extension-koni-ui
  • extension-web-ui
2

Run Full Build

To build the entire extension with all assets:
yarn build
This command runs:
  1. TypeScript compilation (koni-dev-build-ts)
  2. ZIP packaging (build:zip)
  3. Rollup bundling (build:rollup)
3

Build UI Only

To rebuild only the UI components:
yarn build:ui
This uses webpack in production mode to bundle the extension UI from packages/extension-koni.

​
Watch Mode for Development

For active development, use watch mode to automatically rebuild on file changes: 
yarn watch
# or
yarn dev
Watch mode features:
  • Automatically recompiles on file changes
  • Uses webpack in development mode
  • watch-dev includes inline source maps for easier debugging
  • dev:firefox builds Firefox-specific version

Main Build Commands

CommandDescription
yarn buildComplete build: TS compilation + ZIP + Rollup
yarn build:extraBuild i18n and UI components

​
Specialized Builds

CommandDescription

yarn build:releaseProduction release build (GitHub Actions)
yarn build:i18nBuild internationalization files

​
Packaging Commands

CommandDescription
yarn build:zipCreate all ZIP packages
yarn build:zip:dstPackage Chrome build to master-build.zip
yarn build:zip:dst-ffPackage Firefox build to master-build-firefox.zip
yarn build:zip:srcPackage source code to master-src.zip

​
Build Output

After building, you’ll find the output in these locations:

​
Extension Builds

  • Chrome/Edge build: packages/extension-koni/build/
  • Firefox build: packages/extension-koni/build-firefox/

​
ZIP Packages

In the root directory:
  • master-build.zip - Chrome/Edge extension package
  • master-build-firefox.zip - Firefox extension package
  • master-src.zip - Source code archive

​
Production Build

For production releases:
1

Clean Previous Builds

yarn clean
2

Run Release Build

yarn build:release
This script is optimized for CI/CD and includes all necessary steps for a production build.
3

Verify Output

Check that the following files exist:
  • master-build.zip (Chrome)
  • master-build-firefox.zip (Firefox)
  • All builds in packages/extension-koni/build/

​
Web Runner Build

SubWallet also includes a web-based version: 
# Build web runner
yarn web-runner:build

# Build and create ZIP
yarn web-runner:build-zip

# Development server
yarn web-runner:dev

​
Troubleshooting

​
Build Fails After Dependency Update

Run the postinstall script manually: 
yarn postinstall
This applies necessary patches via patch-package.

​
TypeScript Errors

Ensure all packages are properly referenced in tsconfig.json. The extension uses TypeScript project references for the monorepo structure.

​
Out of Memory

For large builds, increase Node.js memory: 
export NODE_OPTIONS="--max-old-space-size=4096"
yarn build

​
Clean Build

If you encounter persistent issues, perform a clean build: 
yarn clean
rm -rf node_modules
yarn install
yarn build
