…when under runfiles Resolves bazel-contrib#1823 which had a repro https://github.com/purkhusid/ts-jest-repro. NB: The repo uses ts_library devmode UMD output so the relative require in the source code will be transformed to an absolute require which will include the workspace name. In 1.5.0: ``` .../sandbox/darwin-sandbox/23/execroot/jest_repro/bazel-out/darwin-fastbuild/bin/test.sh.runfiles/jest_repro/lib.test.js const lib_1 = require("jest_repro/lib"); ``` works as it finds ``` .../sandbox/darwin-sandbox/23/execroot/jest_repro/bazel-out/darwin-fastbuild/bin/test.sh.runfiles/jest_repro/node_modules/jest_repro/lib.js ``` where `test.sh.runfiles/jest_repro/node_modules/jest_repro` is a symlink to the root of the output tree setup by the linker: ``` lrwxr-xr-x 1 greg wheel 165 29 Apr 05:56 .../sandbox/darwin-sandbox/6/execroot/jest_repro/bazel-out/darwin-fastbuild/bin/test.sh.runfiles/jest_repro/node_modules/jest_repro -> .../sandbox/darwin-sandbox/6/execroot/jest_repro/bazel-out/darwin-fastbuild/bin/test.sh.runfiles/jest_repro ``` In 1.6.0: Bug introduced in bazel-contrib#1850 (thanks for tracking down the culprit @alexeagle) where the root symlink is not created properly when under runfiles (such as a jest_test context). Fix is: ``` let runfilesPath = modulePath; if (runfilesPath.startsWith(`${bin}/`)) { runfilesPath = runfilesPath.slice(bin.length + 1); + } else if (runfilesPath === bin) { + runfilesPath = ''; } ``` in `link_node_modules.ts`. NB: This root workspace symlink will be removed in 2.0 as it causes other unrelated issues. PR for that change is in progress bazel-contrib#1797. In 2.0, we recommend either using the prodmode esm output of ts_library for jest_test or switching to ts_project where the output flavor is controlled by your tsconfig. An example of using ts_library esm output of ts_library (output_group 'es6_sources') is `under /internal/linker/test/issue_1823_use_ts_library_esm`. It require babel-jest to transform the esm to commonjs. Alternately, you can control the 'es5_sources' module format of ts_library with the `devmode_module` but this can lead to other issues such as the output no longer being compatible with ts_devserver and karma_web_test which require named-UMD or named-AMD.
