About

The classic Hello World. Electron flavoured.

Develop

Install WinGet.

Install Chocolatey.

Install MSYS2 and Node.js:

choco install -y msys2 --params="'/NoPath'"
choco install -y nodejs

Execute the following commands in a MSYS2 bash session.

Install the dependencies:

winget install --exact --id MichalTrojnara.osslsigncode

To use the updated PATH environment variable, which will now include the newly installed applications, exit the shell session, and open a new one.

Build and package:

make dist

NB This also creates an example code signing certification authority and uses it to sign the binaries.

List the dist app contents, and confirm it has the expected files:

npx asar list dist/win-unpacked/resources/app.asar

Verify the code signature:

osslsigncode verify \
    -in dist/win-unpacked/hello-world-electron.exe \
    -CAfile example-code-signing-ca-crt.pem
osslsigncode verify \
    -in dist/hello-world-electron-setup-1.3.0.exe \
    -CAfile example-code-signing-ca-crt.pem
osslsigncode verify \
    -in dist/hello-world-electron-1.3.0.msi \
    -CAfile example-code-signing-ca-crt.pem

Show the code signature:

NB The signature verification will fail when your host does not trust the example-code-signing CA.

pwsh -Command 'Import-Certificate example-code-signing-ca-crt.pem -CertStoreLocation Cert:/LocalMachine/Root'
pwsh -Command 'Get-AuthenticodeSignature dist/win-unpacked/hello-world-electron.exe | Format-List'
pwsh -Command 'Get-AuthenticodeSignature dist/hello-world-electron-setup-1.3.0.exe | Format-List'
pwsh -Command 'Get-AuthenticodeSignature dist/hello-world-electron-1.3.0.msi | Format-List'

  • electron-builder, to build the msi, uses WiX, which requires administrator-level privileges. For more information see:

  • To disable the validation, edit package.json, and modify the build.msi.additionalLightArgs property to use the -sval (aka skip validation) argument, e.g.:

    {
        "build": {
            "msi": {
                "additionalLightArgs": ["-sval"]
            }
