问题 I found a solution here: Webpack & Typescript image import But i am getting error for this: [ts] Types of property 'src' are incompatible. Type 'typeof import("*.png")' is not assignable to type 'string | undefined'. Type 'typeof import("*.png")' is not assignable to type 'string'. I guess i need to cast import somehow, but cant figure out how. I am doing this in React. I saw that src attribute is defined as string | undefined , that is why error is popping.

How to use paths in tsconfig.json?

由 余生颓废 提交于 2019-11-26 15:46:38
I was reading about path-mapping in tsconfig.json and I wanted to use it to avoid using the following ugly paths: The project organization is a bit weird because we have a mono-repository that contains projects and libraries. The projects are grouped by company and by browser / server / universal. How can I configure the paths in tsconfig.json so instead of: import { Something } from "../../../../../lib/src/[browser/server/universal]/..."; I can use: import { Something } from "lib/src/[browser/server/universal]/..."; Will something else be required in the webpack config? or is the tsconfig
