electron-builder is a cross-platform build automator and packaging tool for Electron applications. It bundles source code and dependencies into platform-specific installers, portable executables, and app store formats for Windows, macOS, and Linux.
The project functions as a distribution pipeline that orchestrates the signing and notarization of binaries to ensure authenticity and bypass security warnings. It also serves as an auto-update orchestrator, preparing application packages and distribution channels to support automatic background software updates.
Its capability surface covers the compilation of native dependencies to match target runtimes, the automation of release publishing to remote hosting providers, and the use of containerized environments for cross-platform builds. It also provides tools for managing application contents via asset filtering and defining operating system file associations.
