The paths mapping you establish in your tsconfig.json is purely a compile-time mapping. It has no effect on the code generated by the TypeScript compiler. Which is why you have a failure at run time. That’s something that has been reported to the TypeScript project, suggesting that tsc should automatically translate module paths in emitted … Read more
Update to @Begandroide’s answer. “Ivy” is no longer considered experimental, and so the Enable-experimental-ivy-prompt is no longer an option. With the latest major version (12.x…) of the Angular Language Service VSCode extension, you must enable the Use legacy View Engine language service option.
Using exclude property of tsconfig.json (at root level), i.e.: { “exclude”: [ “node_modules”, “**/*.spec.ts” ] }
The Error Warning: To load an ES module, set “type”: “module” in the package.json or is caused by the following Bug in ts-node: https://github.com/TypeStrong/ts-node/issues/935 The Bug is closed, and there is a proposal to solve it, but it is still open: https://github.com/TypeStrong/ts-node/issues/1007 I don’t need “type”: “module” in package.json.

One possible solution would be to use two different tsconfig files, one for the tests and one for the production build. tsconfig.json { “compilerOptions”: { “module”: “commonjs”, “target”: “es6”, “outDir”: “./build”, “baseUrl”: “.”, “paths”: { “*”: [“types/*”] }, “strict”: true, } } tsconfig.prod.json { “extends”: “./tsconfig”, “exclude”: [“**/*.test.ts”, “**/*.mock.ts”] } Then point tsc to the … Read more
TLDR; module in tsconfig.json tells the compiler what syntax to use for the modules in the emitted .js files. Frequently used values are “commonjs” (require/module.exports) or “ES2015” (import/export keywords), but there are other module systems. module affects the module syntax of emitted code while target affects the rest. What does Specify module code generation mean? … Read more
I also encountered the same problem, I solved the problem by removing the project property under parserOptions parserOptions: { ecmaFeatures: { jsx: true, }, ecmaVersion: 12, sourceType: ‘module’, // project: ‘tsconfig.json’, tsconfigRootDir: __dirname, },
This can be set up on your tsconfig.json file, as it is a TypeScript 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
TSC compiler alone can’t resolve the alias paths. So in order to make it work you will be required to install additional dev package npm install –save-dev tsc-alias tsc-alias is for replacing alias paths with relative paths after typescript compilation of tsc compiler because the compiler alone can’t resolve the alias paths After that you … Read more
In Webpack 4 you need to specify the options into a use object: use: [{ loader: ‘ts-loader’, options: { configFile: “tsconfig.webpack.json” } }] Complete Webpack config: var path = require(‘path’); module.exports = { entry: path.resolve(__dirname, ‘src’) + ‘/index.ts’, output: { path: path.resolve(__dirname, ‘dist’), filename: ‘your-library-name.js’, }, module: { rules: [ { test: /\.ts$/, use: [{ … Read more
