CONTENTS -------- Debug Contains the Debug build of tools. Release Contains the Release build of tools. IMPORTANT NOTE -------------- CEF/Chromium builds are created using the following host architectures: - Linux: x86-64 (Intel/AMD) - Windows: x86-64 (Intel/AMD) - MacOS: ARM64 (Apple Silicon) Binaries in this tools package must be run on the supported host OS/architecture even in cases where the output targets a different architecture. For example, files targeting a MacOS 64-bit (Intel) application must be created on a MacOS ARM64 (Apple Silicon) host system using the MacOS 64-bit (Intel) tools distribution. USAGE ----- Start with the required host system and the tools distribution that matches your application's target OS/architecture and CEF version. Custom V8 Snapshots Custom startup snapshots [https://v8.dev/blog/custom-startup-snapshots] can be used to speed up V8/JavaScript load time in the renderer process. With CEF this works as follows: 1. Generate a single JavaScript file that contains custom startup data. For example, using https://github.com/atom/electron-link. 2. Execute the `run_mksnapshot` script to create a `v8_context_snapshot.bin` file containing the custom data in addition to the default V8 data. Example: % run_mksnapshot Release /path/to/snapshot.js Note that bin file names include an architecture component on MacOS (e.g. `v8_context_snapshot.[arm64|x86_64].bin`) 3. Replace the existing `v8_context_snapshot.bin` file in the installation folder or app bundle. 4. Run the application and verify in DevTools that the custom startup data exists. For example, electron-link adds a global `snapshotResult` object. Please visit the CEF Website for additional usage information. https://bitbucket.org/chromiumembedded/cef/
