You need to upgrade your eslint version, in the error you can see a bad prefix eslint-plugin- due to some const in eslint/lib/config/plugins.js which was removed in later versions.
I was just looking for the same thing and found this VSCode extension: move-ts It is very young, but seems to be under active development. I tested it on my Windows machine and immediately ran into an issue with backslashes being used. There is, however, already a pull request to fix this (not by me). … Read more
The answer comes from @DenisPshenov’s comment in one of the answers. It’s buried, so I’ll provide it here… Tell Node where the base url is with NODE_PATH environment variable so that it can resolve absolute paths: Linux / macOS NODE_PATH=dist/ node ./dist/index.js Windows Powershell $env:NODE_PATH=”dist/” node ./dist/index.js
in runtime i get this Uncaught ReferenceError: MyBaseClass is not defined Yes you can do that. The code you posted will work fine. However I suspect in your actual code you have it split across multiple files and MyBaseClass is not executed before the code for MyClass. Fix JavaScript ordering or use external modules to … Read more
You may use rootDirs option within tsconfig.json such as: { “compilerOptions”: { “rootDirs”: [ “src”, “tests” ] } } This can be looked up at Typescript documents, on this page (search for Virtual Directories with rootDirs subtitle): Module Resolution
Sections 9.3 and 9.4 of the specification explain this more clearly. I’ll reproduce here some of the examples given in those sections. External modules Suppose the following code is in main.ts. import log = module(“log”); log.message(“hello”); This file references an external module log, defined by whatever log.ts exports. export function message(s: string) { console.log(s); } … Read more
To have something ready for production (and speed it up), you need to package it. I mean transpiling all files into JavaScript ones and concat them the same way Angular2 does for example. This way you will have several modules contained into a single JS file. This way you will reduce the number of HTTP … Read more
Classes can’t match that interface. The closest you can get, I think is this class, which will generate code that functionally matches the interface (but not according to the compiler). class MyType implements MyInterface { constructor { return “Hello”; } } alert(MyType()); This will generate working code, but the compiler will complain that MyType is … Read more
The problem is that we convert observable into different type… with .subscribe – while we should not (it does not return observable) public makeRequest = (): Observable<any> => { return this.myObservable().subscribe( … // this is wrong, we cannot return .subscribe // because it consumes observable and returns ISusbcriber ); } When we have an observable… … Read more
You asked for it. Let’s do some type manipulation to detect if a given type is a union or not. The way it works is to use the distributive property of conditional types to spread out a union to constituents, and then notice that each constituent is narrower than the union. If that isn’t true, … Read more
