Snapcraft Guide (Linux)

    与更广泛的 Linux 社区一起, 规范旨在解决 项目中的许多常见的软件安装问题。 Snaps 是容器化的软件包, 包括所需的依赖项、自动更新和对所有主要 Linux 发行版的工作, 而无需进行系统修改。

    创建 .snap 文件有三种方法:

    1) 使用 electron-forge 或 , 与 snap 支持的两个工具都不在该框中。 这是最简单的选择。 2) 使用 electron-installer-snap, 它采用 electron-packager 的输出。 3) 使用已经创建的 .deb 包。

    在某些情况下，您需要安装 snapcraft 工具。 安装特定发行版的 snapcraft 的指南在这里能看到。

    打包应用程序使用 (或类似工具)。 Make sure to remove node_modules that you don’t need in your final application, since any module you don’t actually need will increase your application’s size.

    结构输出应该看起来大致像这样:

    1. .
    2. └── dist
    3.     └── app-linux-x64
    4.         ├── LICENSE
    5.         ├── LICENSES.chromium.html
    6.         ├── content_shell.pak
    7.         ├── app
    8.         ├── icudtl.dat
    9.         ├── libgcrypt.so.11
    10.         ├── libnode.so

    13.         ├── v8_context_snapshot.bin
    14.         └── version

    From a terminal that has snapcraft in its PATH, run electron-installer-snap with the only required parameter --src, which is the location of your packaged Electron application created in the first step.

    1. npx electron-installer-snap --src=out/myappname-linux-x64

    If you have an existing build pipeline, you can use electron-installer-snap programmatically. For more information, see the Snapcraft API docs.

    1. name: electron-packager-hello-world

    如果要将此示例应用于现有项目：

    • 替代 source: https://github.com/electron/electron-quick-start.git</0 > 为 <code>source: ...
    • 替代所有的 electron-quick-start 为你的项目名称。

    第 2 步：构建 snap

    1. $ snapcraft
    3. <output snipped>
    4. Snapped electron-packager-hello-world_0.1_amd64.snap

    第 4 步：运行 snap

    1. electron-packager-hello-world

    Snapcraft is capable of taking an existing .deb file and turning it into a .snap file. The creation of a snap is configured using a snapcraft.yaml file that describes the sources, dependencies, description, and other core building blocks.

    If you do not already have a .deb package, using electron-installer-snap might be an easier path to create snap packages. However, multiple solutions for creating Debian packages exist, including , electron-builder or .

    For more information on the available configuration options, see the documentation on the snapcraft syntax. Let’s look at an example:

    1. name: myApp
    2. version: '2.0.0'
    3. summary: A little description for the app.
    5.  You know what? This app is amazing! It does all the things
    6.  for you. Some say it keeps you young, maybe even happy.
    7. grade: stable
    8. confinement: classic
    10. parts:
    11.   slack:
    12.     plugin: dump
    13.     source: my-deb.deb
    14.     source-type: deb
    15.     after:
    16.       - desktop-gtk3
    17.     stage-packages:
    18.       - libasound2
    19.       - libnotify4
    20.       - libnspr4
    21.       - libnss3
    22.       - libpcre3
    23.       - libpulse0
    24.       - libxss1
    25.       - libxtst6
    26.   electron-launch:
    27.     plugin: dump
    28.     source: files/
    29.     prepare: |
    30.       chmod +x bin/electron-launch
    32. apps:
    33.   myApp:
    34.     command: bin/electron-launch $SNAP/usr/lib/myApp/myApp
    35.     desktop: usr/share/applications/myApp.desktop
    36.     # Correct the TMPDIR path for Chromium Framework/Electron to ensure
    37.     # libappindicator has readable resources.
    38.     environment:
    39.       TMPDIR: $XDG_RUNTIME_DIR

    Alternatively, if you’re building your snap with strict confinement, you can use the desktop-launch command:

    1. apps:
    2.   myApp:
    3.     # Correct the TMPDIR path for Chromium Framework/Electron to ensure
    4.     # libappindicator has readable resources.
    5.     command: env TMPDIR=$XDG_RUNTIME_DIR PATH=/usr/local/bin:${PATH} ${SNAP}/bin/desktop-launch $SNAP/myApp/desktop
