Scenario: You have a typescript project set up to generate JSON files. The tsconfig.json is properly configured and all dependencies are in place. You've even referred to this related Q&A and ensured that your typescript files are importing the json files. However, when you run tsc, the json files are not being generated.
In an attempt to troubleshoot, you replicate the project in a different location with identical file structure and dependencies, and upon running tsc, the json files are successfully created. Puzzling situation!
Below is a simplified demonstration using node v16.13.2 and yarn v1.22.7
Reference Project
If you have nodejs and yarn installed, you can follow these steps:
pwd
# /tmp/foolib
yarn init -y # initialize a new project
yarn add typescript # only dependency needed for reproduction
export PATH=$(yarn bin):$PATH # ensure `tsc` is in the path
Additional files required:
src/index.ts
import Thing from './moveme.json'
console.log("Hello")
src/moveme.json
{ "foo": "bar" }
tsconfig.json
{
"compilerOptions": {
"module": "commonjs",
"target": "ES2015",
"declarationMap": true,
"esModuleInterop": true,
"resolveJsonModule": true,
"outDir": "./dist",
"skipLibCheck": true,
"declaration": true,
"jsx": "react"
},
"include": [
"src/**/*"
]
}
If you execute
rm -rf dist; export PATH=$(yarn bin):$PATH; tsc; find distdist
dist/index.d.ts
dist/index.d.ts.map
dist/moveme.json
dist/index.js
Another Project
Considering that you might be utilizing the project as a library elsewhere, let's mimic this scenario:
mkdir /tmp/fooproject
cd /tmp/fooproject
yarn init -y # generates package.json, yarn.lock, node_modules
cp -R /tmp/foolib ./node_modules/ # create a local copy
cd node_modules/foolib
tsc
Upon running find dist, you'll notice:
dist
dist/index.d.ts
dist/index.d.ts.map
dist/index.js
Why isn't moveme.json present in the output?
