Simple node module to download the mksnapshot binaries compatible with Electron for creating v8 snapshots.

The major version of this library tracks the major version of the Electron versions released. So if you are using Electron 2.0.x you would want to use an electron-mksnapshot dependency of ~2.0.0 in your package.json file.

Using

npm install --save-dev electron-mksnapshot
mksnapshot.js file.js (--output_dir OUTPUT_DIR).

Running mksnapshot.js will generate both a snapshot_blob.bin and v8_context_snapshot.bin files which are needed to use custom snapshots in Electron. If an output directory isn't specified, the current directory will be used. (Additional mksnapshot args except for --startup_blob are supported, run mksnapshot --help to see options)

Custom Mirror

You can set the ELECTRON_MIRROR or NPM_CONFIG_ELECTRON_MIRROR environment variables to use a custom base URL for downloading mksnapshot zips.

# Electron mirror for China 
ELECTRON_MIRROR="https://npm.taobao.org/mirrors/electron/"
 
# Local mirror 
# Example of requested URL: http://localhost:8080/1.2.0/mksnapshot-v1.2.0-darwin-x64.zip 
ELECTRON_MIRROR="http://localhost:8080/"

Overriding the version downloaded

The version downloaded can be overriden by setting the ELECTRON_CUSTOM_VERSION environment variable.

# Install mksnapshot for Electron v8.3.0 
ELECTRON_CUSTOM_VERSION=8.3.0 npm install

Generating snapshots for ARM hardware

If you need to generate snapshots for Linux on 32 bit ARM, Linux on ARM64, or Windows on ARM64 you will need to install a cross arch mksnapshot on an Intel x64 machine. To do so, set the npm config arch to the proper arch and then run npm install --save-dev electron-mksnapshot. For example:

Linux on ARM64

From an Intel x64 Linux OS run:

npm config set arch arm64
npm install --save-dev electron-mksnapshot

Linux on 32 bit ARM

From an Intel x64 Linux OS run:

npm config set arch armv7l
npm install --save-dev electron-mksnapshot

Windows on ARM (64-bit)

From an Intel x64 Windows OS run:

npm config set arch arm64
npm install --save-dev electron-mksnapshot
