Error: bundle initial-es5 exceeded maximum budget. Budget 6.00 MB was not met by 133.51 kB with a total of 6.13 MB

I have an angular application upgraded to 11.

And I do a > ng build --prod

And I see this information:

√ Browser application bundle generation complete.
√ ES5 bundle generation complete.

But I also get this error:

Error: bundle initial-es5 exceeded maximum budget. Budget 6.00 MB was not met by 133.51 kB with a total of 6.13 MB.

But I already changed the budget size some time ago:

 "budgets": [
                {
                  "type": "initial",
                  "maximumWarning": "4mb",
                  "maximumError": "6mb"
                },
                {
                  "type": "anyComponentStyle",
                  "maximumWarning": "6kb",
                  "maximumError": "10kb"
                }
              ]

Of course, I could again increase the size. But of course, that is not what you want to do.

How to decrease the dist folder?

Thank you

Answer

Sometimes when your application grows there is no other option and you have to raise the bulk size constraints in angular.json to compile.

But first you should try removing useless code, dependencies, assets, styles, etc. in order to reduce size.
