JoostK	7dcf2864a3	feat(compiler-cli): expose function to allow short-circuiting of linking (#40137) ... The linker is implemented using a Babel transform such that Babel needs to parse and walk a source file to find the declarations that need to be compiled. If it can be determined that a source file is known not to contain any declarations the parsing and walking can be skipped as a performance improvement. This commit adds an exposed function for tools that integrate the linker to use to allow short-circuiting of the linker transform. PR Close #40137	2020-12-22 14:53:02 -08:00
Pete Bacon Darwin	7e742aea7c	refactor(compiler-cli): linker - add Babel plugin, FileLinker and initial PartialLinkers (#39116) ... This commit adds the basic building blocks for linking partial declarations. In particular it provides a generic `FileLinker` class that delegates to a set of (not yet implemented) `PartialLinker` classes. The Babel plugin makes use of this `FileLinker` providing concrete classes for `AstHost` and `AstFactory` that work with Babel AST. It can be created with the following code: ```ts const plugin = createEs2015LinkerPlugin({ /* options */ }); ``` PR Close #39116	2020-10-19 11:23:45 -07:00
Pete Bacon Darwin	7dd0db6d4f	refactor(compiler-cli): implement BabelAstFactory and AstHosts (#38866) ... This commit adds the `AstHost` interface, along with implementations for both Babel and TS. It also implements the Babel vesion of the `AstFactory` interface, along with a linker specific implementation of the `ImportGenerator` interface. These classes will be used by the new "ng-linker" to transform prelinked library code using a Babel plugin. PR Close #38866	2020-10-01 09:32:12 -07:00
