appId or productName not found

Error message

appId or productName not found

What it means

This is a build-time error thrown by the Electron pre-build script (buildBefore.ts). The script reads electron-builder.yaml from the project root and regex-matches two keys: 'appId' and 'productName', both expecting a quoted value (single or double quotes). If either regex match returns null, the script throws and calls process.exit(1), aborting the entire Electron build. The regex specifically requires the colon-colon-quote pattern: /appId:\s*['"]([^'"]+)['"].

Solutions

1. Verify electron-builder.yaml exists at the repo root and contains both keys with quoted values, e.g. `appId: "com.example.app"` and `productName: "MyApp"`.
2. If the file is missing, restore it from git or copy from a template and fill in real values.
3. Ensure values are wrapped in single or double quotes — the regex requires them.
4. Run the build script standalone (`node electron/script/buildBefore.ts` or via tsx) to see the exact regex failure before running the full build.

Example fix

// before (electron-builder.yaml)
appId: com.example.app
productName: MyApp

// after (values must be quoted to satisfy the regex)
appId: "com.example.app"
productName: "MyApp"

// Before running the electron build, assert the yaml is well-formed
import fs from 'fs';
import path from 'path';
const yaml = fs.readFileSync(path.join(root, 'electron-builder.yaml'), 'utf-8');
const hasAppId = /appId:\s*['"][^'"]+['"]/.test(yaml);
const hasProductName = /productName:\s*['"][^'"]+['"]/.test(yaml);
if (!hasAppId || !hasProductName) {
  console.error('electron-builder.yaml must define quoted appId and productName');
  process.exit(1);
}

When it happens

Trigger: Running `pnpm build` (or the electron build target) when electron-builder.yaml is missing, is empty, or does not contain both `appId: "..."` and `productName: "..."` lines with quoted values. Also triggered if the keys use YAML flow syntax without quotes (e.g. `appId: com.app` unquoted), or if indentation/comment formatting breaks the single-line regex match.

Common situations: Renaming or relocating electron-builder.yaml; switching between electron and non-electron build configs and forgetting to populate the yaml; YAML values written unquoted; trailing inline comments on the same line (`appId: "x" # comment`) which still match but can confuse downstream; fresh clone where the yaml is gitignored.
