resolveJsonModule json node_modules
🕗 Version & Regression Information
Version 4.2.4
macOS 11.3
The issue seems very old, at least TS v3.4 is also affected.
- This is the behavior in every version I tried, and I reviewed the FAQ for entries about tsconfig.json
💻 Code
tsconfig.json
{
"compilerOptions": {
"baseUrl": "src",
"rootDir": "src",
"outDir": "dist",
"resolveJsonModule": true,
},
}src/index.ts
import * as json from './config.json';src/config.json
{}🙁 Actual behavior
When I run tsc the output in dist contains index.js and config.json. This is good and expected. If any parent directory is named node_modules then the JSON file will no longer be copied. A full terminal session of this phenomenon is included below:
marcel@marcel ~/tmp $ ls -lah
total 0
drwxr-xr-x 3 marcel staff 96B May 4 02:22 .
drwxr-xr-x 84 marcel staff 2.6K May 4 02:22 ..
drwxr-xr-x 4 marcel staff 128B May 4 02:21 test
marcel@marcel ~/tmp $ cd test
marcel@marcel ~/tmp/test $ ls -lah
total 8
drwxr-xr-x 4 marcel staff 128B May 4 02:21 .
drwxr-xr-x 3 marcel staff 96B May 4 02:22 ..
drwxr-xr-x 4 marcel staff 128B May 4 02:13 src
-rw-r--r-- 1 marcel staff 119B May 4 02:14 tsconfig.json
marcel@marcel ~/tmp/test $ npx tsc
marcel@marcel ~/tmp/test $ cat dist/config.json
{}
marcel@marcel ~/tmp/test $ cd ..
marcel@marcel ~/tmp $ mkdir node_modules
marcel@marcel ~/tmp $ mv test node_modules
marcel@marcel ~/tmp $ cd node_modules/test
marcel@marcel ~/tmp/node_modules/test $ rm -rf dist
marcel@marcel ~/tmp/node_modules/test $ npx tsc
marcel@marcel ~/tmp/node_modules/test $ cat dist/config.json
cat: dist/config.json: No such file or directory
marcel@marcel ~/tmp/node_modules/test $ ls dist
index.js
🙂 Expected behavior
It is unexpected that the name of a parent directory would affect the compiler in this manner.
Additional information
If I invoke the compiler with the --traceResolution option the output is almost exactly the same but an additional line is logged in the node_modules parent case. The full log follows and the additional line is annotated inline. This diagnostic message does not appear when node_modules is found in the parent hierarchy.
