The partial compiler will add a version number to the objects that are generated so that the linker can select the appropriate partial linker class to process the metadata. Previously this version matching was a simple number check. Now the partial compilation writes the current Angular compiler version into the generated metadata, and semantic version ranges are used to select the appropriate partial linker. PR Close #39847 |

Angular Linker
This package contains a FileLinker and supporting code to be able to "link" partial declarations of components, directives, etc in libraries to produce the full definitions.
The partial declaration format allows library packages to be published to npm without exposing the underlying Ivy instructions.
The tooling here allows application build tools (e.g. CLI) to produce fully compiled components, directives, etc at the point when the application is bundled.
These linked files can be cached outside node_modules so it does not suffer from problems of mutating packages in node_modules.
Generally this tooling will be wrapped in a transpiler specific plugin, such as the provided Babel plugin.
Unit Testing
The unit tests are built and run using Bazel:
yarn bazel test //packages/compiler-cli/linker/test
