Angular 19 Application Builder (ESBuild) - ESM Incompatibility with prettier/standalone

[souravion]

Problem description

A build error occurs when deploying an Angular 19 project to Netlify, using the @angular-devkit/build-angular:application builder. The error indicates an incompatibility related to prettier/standalone, used as a CommonJS module within the @stedi/prettier-plugin-jsonata package. The full error message is:

prettier/standalone' used by 'node_modules/@stedi/prettier-plugin-jsonata/dist/lib/index.js' is not ESM

Steps to reproduce

• Create a new Angular 19 project using the Angular CLI.
• Install @stedi/prettier-plugin-jsonata and Prettier (version 3.0 or later).
• Configure angular.json to use the @angular-devkit/build-angular:application builder.
• Ensure esModuleInterop: true is set in tsconfig.json.
• Attempt to build the project (ng build --configuration production) or deploy it to Netlify.

Expected behavior

The Angular 19 application should build and deploy successfully without errors related to module resolution or ESM/CommonJS incompatibility.

Troubleshooting steps attempted

• Confirmed esModuleInterop: true is present in tsconfig.json.
• Added @stedi/prettier-plugin-jsonata to allowedCommonJsDependencies within the build options in angular.json, notes GitHub,.
• Ensured the Node.js version in the Netlify build environment is 18 or later, compatible with Angular 19 and Prettier 3+.
• Verified that Prettier version 3.0 or later is installed in the project

Environment details

• Angular Version: 19.0.0
• Angular CLI Version: 17.3.13
• Builder: @angular-devkit/build-angular:application
• Node.js Version 20.15.1
• @stedi/prettier-plugin-jsonata Version: ^2.1.5
• Deployment Platform: Netlify

Various troubleshooting steps, including setting allowedCommonJsDependencies, were explored, but the issue persists. This indicates a potential deeper incompatibility between the plugin's structure and the Angular 19 application builder's ESM-first approach. Any guidance or potential solutions would be appreciated
