electron-osx-sign
A Node.js library for codesigning Electron macOS apps and creating .pkg installers.
What is electron-osx-sign?
@electron/osx-sign is a Node.js library that simplifies code signing and installer creation for Electron applications on macOS. It automates the use of Apple's `codesign` and `productbuild` utilities, handling the technical requirements for distributing apps on the Mac App Store or via direct download. The tool integrates with popular Electron packaging pipelines like Electron Packager and Electron Forge.
Electron developers targeting macOS distribution, particularly those needing to sign apps for the Mac App Store or create .pkg installers. It's also useful for developers maintaining legacy Electron applications.
Developers choose @electron/osx-sign because it reduces the complexity of macOS code signing with sensible defaults, provides a programmatic API for automation, and maintains compatibility with older Electron versions. Its integration with Electron's ecosystem makes it a trusted, official solution.
Overview
Codesign Electron macOS apps
Use Cases
Best For
- Signing Electron apps for Mac App Store submission
- Creating .pkg installer packages for direct macOS distribution
- Automating code signing in CI/CD pipelines for Electron projects
- Handling provisioning profiles and certificate management for macOS apps
- Signing legacy Electron applications with older macOS compatibility requirements
- Applying deep signing to specific subresources within an Electron app bundle
Not Ideal For
- Non-Electron macOS application development, as the tool is specifically designed for Electron .app bundles
- Teams using all-in-one packaging solutions like electron-builder that handle signing internally, adding redundancy
- Developers requiring granular control over the codesign process beyond the provided API, where direct command-line usage is necessary
- Projects exclusively targeting Linux or Windows platforms, since this tool is macOS-exclusive
Pros & Cons
Pros
Works out of the box for most Electron apps by automatically detecting certificates and minimizing configuration, as stated in the README's philosophy of reducing manual effort.
Offers fine-grained control through options like per-file signing with `optionsForFile`, allowing customization for specific subresources such as applying --deep signing selectively.
Seamlessly integrates with popular Electron tools like Electron Packager and Electron Forge, reducing setup effort in existing packaging pipelines.
Maintains backwards compatibility with older, unsupported versions of Electron by allowing version specification, ensuring long-term project viability.
Cons
The command-line interface is labeled as legacy and lacks full API features, such as `optionsForFile`, forcing developers to use the JavaScript API for advanced use cases.
Signing for Mac App Store distribution can prevent local execution without manual entitlement adjustments, adding extra steps for testing as noted in the README's warning about `preAutoEntitlements`.
Requires Xcode, Apple developer certificates, and provisioning profiles, which involve additional setup, costs, and potential security concerns with third-party sources.
