How to add "portable" to the electron builder .exe file name? - electron-builder

Question

This is my package.json build data:
"build": {
"appId": "name.desktop",
"productName": "name",
"beforePack": "electron/beforePack.js",
"extraResources": [
{
"from": "bin/${os}",
"to": "bin",
"filter": [
"**/*"
]
}
],
"files": [
"build/**/*",
"electron/**/*",
"package.json"
],
"extends": null,
"mac": {
"target": "dmg",
"type": "distribution"
},
"win": {
"target": [
"portable",
"nsis"
]
},
"linux": {
"target": "AppImage"
}
}
I'm looking to add "portable" to the windows portable file name, so that the .exe is "name 1.0.0 portable.exe" instead of "name 1.0.0.exe"

Answer 1

It is possible to explicitely define the generated file names at each relevant level in the package.json file by making use of an "artifactName" property.
This is documented in the Overridable per Platform Options section of the Common Configuration - electron-builder page:
Following options can be set also per platform (top-level keys mac, linux and win) if need.
artifactName String | “undefined” - The artifact file name template. Defaults to ${productName}-${version}.${ext} (some target can have other defaults, see corresponding options).
which indirectly refers to the File Macros section of the File Patterns - electron-builder page.
In your specific case, you'll have to add the following "artifactName" property to your package.json file at the Windows version level:
"artifactName": "${name} ${version} portable.${ext}",
i.e.:
"build": {
"appId": "name.desktop",
"productName": "name",
"beforePack": "electron/beforePack.js",
"extraResources": [
{
"from": "bin/${os}",
"to": "bin",
"filter": [
"**/*"
]
}
],
"files": [
"build/**/*",
"electron/**/*",
"package.json"
],
"extends": null,
"mac": {
"target": "dmg",
"type": "distribution"
},
"win": {
"artifactName": "${name} ${version} portable.${ext}",
"target": [
"portable",
"nsis"
]
},
"linux": {
"target": "AppImage"
}
}
