Arguments The argument for ng build command is as follows − Sr.No. Argument & Syntax Description 1 <project> The name of the application or library to be built. Options Options are optional parameters. Sr.No. Option & Syntax Description 1 –aot=true|false Build using Ahead of Time compilation. Default: false. 2 –baseHref=baseHref Base url for the application being built. 3 –buildEventLog=buildEventLog EXPERIMENTAL Output file path for Build Event Protocol events. 4 –buildOptimizer=true|false Enables ”@angular-devkit/build-optimizer” optimizations when using the ”aot” option. Default: false. 5 –commonChunk=true|false Use a separate bundle containing code used across multiple bundles. Default: false. 6 –configuration=configuration A named build target, as specified in the “configurations” section of angular.json. Each named target is accompanied by a configuration of option defaults for that target. Setting this explicitly overrides the “–prod” flag. Aliases: -c. 7 –crossOrigin=none|anonymous|use-credentials Define the crossorigin attribute setting of elements that provide CORS support. Default: none. 8 –deleteOutputPath=true|false Delete the output path before building. Default: true. 9 –deployUrl=deployUrl URL where files will be deployed. 10 –experimentalRollupPass=true|false Concatenate modules with Rollup before bundling them with Webpack.

Default: false. 27 –prod=true|false Shorthand for “–configuration=production”. When true, sets the build configuration to the production target. By default, the production target is set up in the workspace configuration such that all builds make use of bundling, limited tree-shaking, and also limited dead code elimination. 28 –progress=true|false Log progress to the console while building. Default: true. 27 –resourcesOutputPath=resourcesOutputPath The path where style resources will be placed, relative to outputPath. 28 –serviceWorker=true|false Generates a service worker config for production builds.
