[Bug]: typescript 5.5.2 cannot find input files with source tsconfig.json

[gzm0]

What happened?

Minimal reproducible example below.

With TS 5.5.2, sources cannot be found:

Version

Development (host) and target OS/architectures:

Output of bazel --version:

bazel --version
bazel 7.2.1

Version of the Aspect rules, or other relevant rules from your
WORKSPACE or MODULE.bazel file:

bazel_dep(name = "aspect_rules_ts", version = "2.4.2")

rules_ts_ext = use_extension("@aspect_rules_ts//ts:extensions.bzl", "ext", dev_dependency = True)

rules_ts_ext.deps(
    # TS 5.5.2, broken:
    ts_version="5.5.2",

How to reproduce

MODULE.bazel from above.

BUILD.bazel:

load("@aspect_rules_ts//ts:defs.bzl", "ts_project")

ts_project(
    name = "test",
    srcs = ["test.ts"],
)

tsconfig.json

{}

.bazelrc

common --@aspect_rules_ts//ts:skipLibCheck=always
common --@aspect_rules_ts//ts:default_to_tsc_transpiler

test.ts

console.log("foo");

Then run bazel build //:test

Any other information?

The tsconfig.json must be a source file.

If you do (and optionally delete tsconfig.json), the issue vanishes.

 ts_project(
     name = "test",
     srcs = ["test.ts"],
+    tsconfig = {},
 )

[gzm0]

Further investigation shows that the difference between a source tsconfig.json and a generated tsconfig.json is the files parameter. If I add it to tsconfig.json ({ "files": ["test.ts"] }), everything compiles again.

[gzm0]

My gut tells me that microsoft/TypeScript#58042 could have changed how relative paths with symlinks are resolved but I cannot find any evidence of that.

I'm currently double-checking that I cannot reproduce this issue without rules_ts.

[gzm0]

I have double checked that when running bare typescript (npx tsc), the error does not occur.

Specifying exclude: [] fixes the issue. It looks like typescript 5.5 adds the outDir passed via command line to exclude.

typescript 5.4 doesn't do that as can be shown experimentally (by setting a bogus include pattern):

TS 5.4:

error TS18003: No inputs were found in config file '/home/tos/.cache/bazel/_bazel_tos/287294dcdaea82c1370bff9bd5064654/sandbox/linux-sandbox/1051/execroot/_main/bazel-out/k8-fastbuild/bin/src/tsconfig.json'. Specified 'include' paths were '["**/*.tsx"]' and 'exclude' paths were '[]'.

TS 5.5 (note the differently reported exclude pattern):

error TS18003: No inputs were found in config file '/home/tos/.cache/bazel/_bazel_tos/287294dcdaea82c1370bff9bd5064654/sandbox/linux-sandbox/1054/execroot/_main/bazel-out/k8-fastbuild/bin/src/tsconfig.json'. Specified 'include' paths were '["**/*.tsx"]' and 'exclude' paths were '["/home/tos/.cache/bazel/_bazel_tos/287294dcdaea82c1370bff9bd5064654/sandbox/linux-sandbox/1054/execroot/_main/bazel-out/k8-fastbuild/bin/src"]'.

So a workaround is to override exclude manually.

I filed this upstream: microsoft/TypeScript#59036

[gzm0]

TY @alexeagle. Please LMK if there is anything I can help.

For discoverability:

workaround

add exclude: [] to your tsconfig.json.

[alexeagle]

I'll adopt that workaround to land the new version mirroring: #643

We'll see if there's progress from TS team, if not then I'll have to detect the error message and print the workaround :(

It's so gross :( :( https://github.com/aspect-build/rules_ts/pull/646/files
