TypeScript does not auto-polyfill code (see microsoft/TypeScript#3101). The “official” reason from the relevant GitHub issue seems to be, as @RyanCavanaugh said: Having the compiler try to figure out which [ES20XX] methods you need, and where to emit them, and when, with controls for people who don’t want the polyfills emitted, and ways to change where … Read more
I ended up defining multiple config files and use extends to simplify them. Say I have two files: tsconfig.json and tsconfig.build.json // tsconfig.json { … “exclude”: […] } // tsconfig.build.json { … “files”: [ “typings/index.d.ts”, “src/index.ts” ] } This way, I can have fine control on what to build (using tsc -p tsconfig.build.json) and what … Read more
Quickfix is to skip the check { “compilerOptions”: { “skipLibCheck”: true }, }
I am quite new to Typescript. What does Target in tsconfig.json signify? target signifies which target of JavaScript should be emitted from the given TypeScript. Examples: target:es5 ()=>null will become function(){return null} as ES5 doesn’t have arrow functions. target:es6 ()=>null will become ()=>null as ES6 has arrow functions. More I also made a quick video … Read more
One of the ways to get rid of that error is by modifying d.ts file as follows: declare module “*.png” remove { const value: string; export default value; } or alternatively you can do: declare module “*.png” { const value: any; export default value; } Update The best solution with type-checking is: declare module “*.png” … Read more
This is possible, and it turns out, not hard. The reason the solution is not obvious is because typescript relies on the rootDir to decide the directory structure of the output (see this comment from Typescript’s bossman), and only code included in the output or in package dependencies can be imported. If you set rootDir … Read more
This can be set up on your tsconfig.json file, as it is a TS feature. You can do like this: “compilerOptions”: { “baseUrl”: “src”, // This must be specified if “paths” is. … “paths”: { “@app/*”: [“app/*”], “@config/*”: [“app/_config/*”], “@environment/*”: [“environments/*”], “@shared/*”: [“app/_shared/*”], “@helpers/*”: [“helpers/*”] }, … Have in mind that the path where you … Read more
