The linker inserts the constant statements that are needed to support compiled templates after the import statements of an ESM file, but it failed to account for import statements that are not at the top of the file. This is typically seen in FESM files where multiple individual ESMs have been concatenated into a single ESM file, with imports in various places. The linker would then find the very last import statement to insert the constant statements after, but this may result in TDZ errors for component templates that have been emitted earlier in the file. This commit updates the Babel linker plugin to insert constant statements after the last import of the first import group, therefore avoiding the TDZ error. Fixes #56403 PR Close #56431 |

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
