Output folder:
dist/out-tsc
handler.js -> fn.getAll
After typescript compile using tsc. output files are generated at targeted location. In each JS handler file i have tslib require statement. Below error message denotes the same. When I click on the tslib it refers to the node modules perfectly. How can I overcome this?
I have updated the tsconfig.json with below options in compileroptions. Installed tslib in node modules
"paths": {
"tslib": ["node_modules/tslib/tslib.d.ts"]
}
