Description
I've been trying to switch our project to the experimental esbuild in a hope to get our build times down from ~3 minutes.
I've added an extra architect option to our angular.json file.
"esbuild": {
"builder": "@angular-devkit/build-angular:browser-esbuild",
"options": {
"outputPath": "dist/",
"index": "src/client/dummy.html",
"main": "src/client/index.ts",
"polyfills": "src/client/polyfills.ts",
"tsConfig": "tsconfig.json",
"inlineStyleLanguage": "scss",
"assets": [
"src/client/assets"
],
"scripts": []
},
"configurations": {
"development": {
"buildOptimizer": false,
"optimization": false,
"vendorChunk": true,
"extractLicenses": false,
"sourceMap": true,
"namedChunks": true
}
},
"defaultConfiguration": "development"
},
I then run this particular configuration with ng run core:esbuild --watch.
It builds fine in about 90-100 seconds in the first attempt, but after an initial change, the file watcher keeps on seeing a change and will try to rebuild.
Complete. [8.351 seconds]
Changes detected. Rebuilding...
It will even start doing this if you build initially and wait long enough.
I've tried to create a test case by creating a new Angular project and adding the same changes to angular.json, but there the filewatcher works fine and only builds once after a change.
I'm wondering what it could be that keeps triggering these file changes.
Minimal Reproduction
As described above:
- added architect option to angular.json file with experimental esbuild pipeline
- run particular configuration with
ng run core:esbuild --watch
