Migration from version 12 to version 13

Custom Webpack builder

Jest builder

jest-preset-angular has been updated to version 11.

  • If you use it without custom configuration then no action required.
  • If you use it with custom configuration, you might need to update it.

Migration from version 11 to version 12

Custom Webpack builder

No breaking changes (except for updating to Angular 12)

Jest builder (since 12.1.0)

  1. Jest 27 is required now
  2. jest-preset-angular has been updated to version 9, which uses Angular compiler instead of ts-jest in order to transform the TS files. Make sure you understand the implications and perform all the necessary changes to your code base as described in jest-preset-angular CHANGELOG.

Migration from version 10 to version 11

Custom Webpack builder

  1. mergeStrategies field in customWebpackConfig has been deprecated, use mergeRules instead as defined here.

In order to make this breaking change as backward compatible as possible, the default value of mergeRules is the following:

{
  module: {
    rules: {
      test: "match",
      use: {
        loader: "match",
        options: "merge",
      },
    },
  },
};

This is as close as possible to the smart merge strategy that was used before, so ideally if you didn't use mergeStrategies then your configuration should work just as it worked before.
Otherwise you'll have to adjust the mergeRules in accordance with your needs.
If you don't want to invest time in learning how the mergeRules work or you have a complicated use case then consider using Custom Webpack Config Function. This way you'll have full control over the configuration without relying on any merging mechanism.

Migration from version 9 to version 10

Jest builder

  1. Update to Jest 26 if you still haven't.

Migration from version 8 to version 9

All builders

  1. @angular/architect and angular/core are now direct builder dependencies, therefore no need to specify them explicitly in package.json

Jest builder

  1. jest-preset-angular version has been updated to 8. If you have any custom Jest configuration, make sure it matches the preset version.

  2. If you're using Ivy (enabled by default in version 9) make sure you run ngcc in a postinstall hook. For more details refer to this issue.

Migration from version 7 to version 8

Custom Webpack builder

  1. index.html is no longer generated with Webpack. This means if your solution uses Webpack to alter index.html it will stop working the moment you upgrade to version 8.
    Instead you should use indexTransform property.

Dev-server builder

  1. @angular-builders/dev-server:generic has been deprecated. Use @angular-builders/custom-webpack:dev-server instead.

Jest builder

  1. Update to Jest 24 if you still haven't.
