# Vite Electron Builder Boilerplate
----
> Vite+Electron = 🔥
This is a template for secure electron applications. Written following the latest safety requirements, recommendations
and best practices.
Under the hood is [Vite] — A next-generation blazing fast bundler, and [electron-builder] for packaging.
## Get started
Follow these steps to get started with the template:
1. Click the **[Use this template](https://github.com/cawa-93/vite-electron-builder/generate)** button (you must be
logged in) or just clone this repo.
2. If you want to use another package manager don't forget to edit [`.github/workflows`](/.github/workflows) -- it
uses `npm` by default.
That's all you need. 😉
**Note**: This template uses npm v7 feature — [**Installing Peer Dependencies
Automatically**](https://github.com/npm/rfcs/blob/latest/implemented/0025-install-peer-deps.md). If you are using a
different package manager, you may need to install some peerDependencies manually.
**Note**: Find more useful forks [here](https://github.com/cawa-93/vite-electron-builder/discussions/categories/forks).
## Features
### Electron [][electron]
- This template uses the latest electron version with all the latest security patches.
- The architecture of the application is built according to the
security [guides](https://www.electronjs.org/docs/tutorial/security) and best practices.
- The latest version of the [electron-builder] is used to package the application.
### Vite [][vite]
- [Vite] is used to bundle all source codes. It's an extremely fast bundler, that has a vast array of amazing features.
You can learn more about how it is arranged in [this](https://www.youtube.com/watch?v=xXrhg26VCSc) video.
- Vite [supports](https://vitejs.dev/guide/env-and-mode.html) reading `.env` files. You can also specify the types of
your environment variables in [`types/env.d.ts`](types/env.d.ts).
- Automatic hot-reloads for the `Main` and `Renderer` processes.
Vite provides many useful features, such as: `TypeScript`, `TSX/JSX`, `CSS/JSON Importing`, `CSS Modules`
, `Web Assembly` and much more.
[See all Vite features](https://vitejs.dev/guide/features.html).
### TypeScript [][typescript] (optional)
- The latest version of TypeScript is used for all the source code.
- **Vite** supports TypeScript out of the box. However, it does not support type checking.
- Code formatting rules follow the latest TypeScript recommendations and best practices thanks
to [@typescript-eslint/eslint-plugin](https://www.npmjs.com/package/@typescript-eslint/eslint-plugin).
**[See this discussion](https://github.com/cawa-93/vite-electron-builder/discussions/339)** if you want completely
remove TypeScript.
### Vue [][vue] (optional)
- By default, web pages are built using [Vue]. However, you can easily change that. Or not use additional frameworks at
all.
- Code formatting rules follow the latest Vue recommendations and best practices thanks to [eslint-plugin-vue].
See [examples of web pages for different frameworks](https://github.com/vitejs/vite/tree/main/packages/create-vite).
### Continuous Integration
- The configured workflow will check the types for each push and PR.
- The configured workflow will check the code style for each push and PR.
- **Automatic tests**
used [Vitest ][vitest]
-- A blazing fast test framework powered by Vite.
- Unit tests are placed within each package and are ran separately.
- End-to-end tests are placed in the root [`tests`](tests) directory and use [playwright].
### Continuous delivery
- Each time you push changes to the `main` branch, the [`release`](.github/workflows/release.yml) workflow starts, which
creates a release draft.
- The version is automatically set based on the current date in the format `yy.mm.dd-minutes`.
- Notes are automatically generated and added to the release draft.
- Code signing supported. See [`compile` job in the `release` workflow](.github/workflows/release.yml).
- **Auto-update is supported**. After the release is published, all client applications will download the new version
and install updates silently.
## How it works
The template requires a minimum amount [dependencies](package.json). Only **Vite** is used for building, nothing more.
### Project Structure
The structure of this template is very similar to the structure of a monorepo.
```mermaid
flowchart TB;
packages/preload <-. IPC Messages .-> packages/main
subgraph packages/main
M[index.ts] --> EM[Electron Main Process Modules]
M --> N2[Node.js API]
end
subgraph packages/preload
P[index.ts] --> N[Node.js API]
P --> ED[External dependencies]
P --> ER[Electron Renderer Process Modules]
end
subgraph packages/renderer
R[index.html] --> W[Web API]
R --> BD[Bundled dependencies]
R --> F[Web Frameforks]
end
packages/renderer -- Call Exposed API --> P
```
The entire source code of the project is divided into three modules (packages) that are each bundled independently:
- [`packages/renderer`](packages/renderer). Responsible for the contents of the application window. In fact, it is a
regular web application. In developer mode, you can even open it in a browser. The development and build process is
the same as for classic web applications. Access to low-level API electrons or Node.js is done through the _preload_
layer.
- [`packages/preload`](packages/preload). Acts as an intermediate bridge between the _renderer_ process and the API
exposed by electron and Node.js. Runs in an _isolated browser context_, but has direct access to the full Node.js
functionality.
See [Checklist: Security Recommendations](https://www.electronjs.org/docs/tutorial/security#2-do-not-enable-nodejs-integration-for-remote-content)
.
- [`packages/main`](packages/main)
Electron [**main script**](https://www.electronjs.org/docs/tutorial/quick-start#create-the-main-script-file). This is
the main process that powers the application. It manages creating and handling the spawned BrowserWindow, setting and
enforcing secure permissions and request handlers. You can also configure it to do much more as per your need, such
as: logging, reporting statistics and health status among others.
### Build web resources
The `main` and `preload` packages are built in [library mode](https://vitejs.dev/guide/build.html#library-mode) as it is
simple javascript.
The `renderer` package builds as a regular web app.
### Compile App
The next step is to package a ready to distribute Electron app for macOS, Windows and Linux with "auto update" support
out of the box.
To do this, use [electron-builder]:
- Using the npm script `compile`: This script is configured to compile the application as quickly as possible. It is not
ready for distribution, it is compiled only for the current platform and is used for debugging.
- Using GitHub Actions: The application is compiled for any platform and ready-to-distribute files are automatically
added as a draft to the GitHub releases page.
### Working with dependencies
Because the `renderer` works and builds like a _regular web application_, you can only use dependencies that support the
browser or compile to a browser-friendly format.
This means that in the `renderer` you are free to use any frontend dependencies such as Vue, React, lodash, axios and so
on.However, you _CANNNOT_ use any native Node.js APIs, such as, `systeminformation`. These APIs are _only_ available in
a Node.js runtime environment and will cause your application to crash if used in the `renderer` layer. Instead, if you
need access to Node.js runtime APIs in your frontend, export a function form the `preload` package.
All dependencies that require Node.js api can be used in
the [`preload` script](https://www.electronjs.org/docs/latest/tutorial/process-model#preload-scripts).
Here is an example. Let's say you need to read some data from the file system or database in the renderer.
In the preload context, create a function that reads and returns data. To make the function announced in the preload
available in the render, you usually need to call
the [`electron.contextBridge.exposeInMainWorld`](https://www.electronjs.org/ru/docs/latest/api/context-bridge). However,
this template uses the [unplugin-auto-expose](https://github.com/cawa-93/unplugin-auto-expose) plugin, so you just need
to export the method from the preload. The `exposeInMainWorld` will be called automatically.
```ts
// preload/index.ts
import {writeFile} from 'fs'
// Everything you exported from preload/index.ts may be called in renderer
export function getData() {
return /* ... */
}
```
Now you can import and call the method in renderer
```ts
// renderer/somewere.component.ts
import {getData} from '#preload'
const dataFromFS = getData()
```

.
### Working with Electron API
Although the preload has access to all of Node.js's API, it **still runs in the BrowserWindow context**, so a limited
electron modules are available in it. Check the [electron docs](https://www.electronjs.org/ru/docs/latest/api/clipboard)
for full list of available methods.
All other electron methods can be invoked in the `main`.
As a result, the architecture of interaction between all modules is as follows:
```mermaid
sequenceDiagram
renderer->>+preload: Read data from file system
preload->>-renderer: Data
renderer->>preload: Maximize window
activate preload
preload-->>main: Invoke IPC command
activate main
main-->>preload: IPC response
deactivate main
preload->>renderer: Window maximized
deactivate preload
```
[Read more about Inter-Process Communication](https://www.electronjs.org/docs/latest/tutorial/ipc)
### Modes and Environment Variables
All environment variables are set as part of the `import.meta`, so you can access them vie the following
way: `import.meta.env`.
If you are using TypeScript and want to get code completion you must add all the environment variables to
the [`ImportMetaEnv` in `types/env.d.ts`](types/env.d.ts).
The mode option is used to specify the value of `import.meta.env.MODE` and the corresponding environment variables files
that need to be loaded.
By default, there are two modes:
- `production` is used by default
- `development` is used by `npm run watch` script
When running the build script, the environment variables are loaded from the following files in your project root:
```
.env # loaded in all cases
.env.local # loaded in all cases, ignored by git
.env.[mode] # only loaded in specified env mode
.env.[mode].local # only loaded in specified env mode, ignored by git
```
To prevent accidentally leaking env variables to the client, only variables prefixed with `VITE_` are exposed to your
Vite-processed code.
For example let's take the following `.env` file:
```
DB_PASSWORD=foobar
VITE_SOME_KEY=123
```
Only `VITE_SOME_KEY` will be exposed as `import.meta.env.VITE_SOME_KEY` to your client source code, but `DB_PASSWORD`
will not.
