# Example for using custom v8 snapshots in an Electron app
Generate a custom v8 snapshots using [electron-link](https://github.com/atom/electron-link) and [mksnapshot](https://github.com/electron/mksnapshot).
Read [the blog article](https://blog.inkdrop.info/how-to-make-your-electron-app-launch-1000ms-faster-32ce1e0bb52c) for detail.
## How to install
```sh
ELECTRON_CUSTOM_VERSION=13.0.1 npm install
```
## How it works
### Generate v8 snapshots
Run the following command:
```sh
npm run generate-v8-snapshots
```
It generates v8 snapshots containing `react` and `react-dom` libraries from `/snapshot.js`.
You should get `v8_context_snapshot.bin` in the project directory.
### Copy the snapshots into Electron
```sh
npm run copy-v8-snapshots
```
It copies `snapshot_blob.bin` and `v8_context_snapshot.bin` files to the Electron's binary.
### Start the Electron app
The electron app will load those libraries from the snapshots.
You should get a window like so:
As you can see, `react` and `react-dom` libraries are loaded from the v8 snapshot cache.
