Mocked File system:
/ project / included / in / file.ts > File which shall require the ".js" file
/ project / root / of / file.js > Bundled file
/ project / root / of / file.d.ts > Bundled declarations filein tsconfig.json:
{
"compilerOptions": {
...
"moduleResolution": "node",
"baseUrl": ".",
"paths": {
"/*": [
"./*"
]
}
},
}When running "tsc --traceResolution" the compiler successfully finds the .js file, resolving the module name, but does not lookup for .d.ts file:
======== Resolving module '/root/of/file.js' from '/project/included/in/file.ts'. ========
Explicitly specified module resolution kind: 'NodeJs'.
'baseUrl' option is set to '/project', using this value to resolve non-relative module name '/root/of/file.js'.
'paths' option is specified, looking for a pattern to match module name '/root/of/file.js'.
Module name '/root/of/file.js', matched pattern '/*'.
Trying substitution './*', candidate module location: './root/of/file.js'.
File '/project/root/of/file.js' exist - use it as a name resolution result.
======== Module name '/root/of/file.js' was successfully resolved to '/project/root/of/file.js'. ========As seen in the log messages TSC is able to resolve the .js file but does not load the "file.d.ts" standing right next to it!
Expected behavior:
When specifying a path ending with ".js", required for browser module resolution, Typescript should be able to locate the corresponding declaration file with a matching name on the same directory!
Removing the slash from the beginning, "root/of/file.js", makes Typescript correctly identify the .d.ts file, but browsers complain of non-relative paths...
Actual behavior:
Compiler / Typescript stops the resolution on the ".js" file failing to import type definitions therefore outputting the following error:
"Could not find a declaration file for module '/root/of/file.js'. '/project/root/of/file.js' implicitly has an 'any' type."
