Esbuild can take
.ts
files as an input and compile to js, this change allows that, and shows that you can plumb together bothesbuild
,ts_project
andjs_library
in novel ways to compile Typescript and bundle it.It's a little tricky to handle the
entry_point
, as we resolve a.ts
entrypoint to its js for the user. This change means that if a.ts
file is passed toentry_point
then it's expected to be insrcs
, rather thandeps
.As a breaking change in 4.0.0, I'd like to propose that we don't automagically resolve to a
.js
input, and the user has to specify the correct extension, or at least provide a flag to flip to the new behaviour, or back to thelegacy_resolve_ts_entry_points
(I like verbose names).closes #2594
