Typescript definition file not being recognized?


Typescript definition file not being recognized?

around this issue I'm trying to use the angular-spinner directive in my app. Since I'm using typescript, I wanted to create a definition file for it. (I know there's one from definitelyTyped, however it's not available using bower anymore and I don't want to use another package manager) ,
Warning: Error: Can't resolve dependency for controller XXX

will help you If you don't control the original definition file, and can't make adjustments to it, then unfortunately, what you're trying to do isn't supported currently in TypeScript. An interface in TypeScript is the only construct that allows reasonable extensions as it is only a compile-time/syntax check and not a run-time operation.
You cannot extend a class in TypeScript with new functionality using only TypeScript (and expecting code-completion/Intellisense to work as expected). You could of course add the functions to the prototype for the CircleMarker class, but they would be unavailable to Intellisense and would fail to compile unless you use a type assertion.
code :
declare module L {
    export interface CircleMarkerEx {
        bindLabel(name: string, options: any): CircleMarker;
    }
}
var cm = <L.CircleMakerEx> circle.bindLabel("name", {});

hope this fix your issue Your module should include it's own node.d.ts file among your .d.ts file (let's call it my_awesome_lib.d.ts)
In your .d.ts file you may include the necessary types as following:
code :
declare module 'my_awesome_lib' {
  import * as express from 'express'; // just as example
  import { EventEmitter } from 'events'; // here you go
  export function foo(EventEmitter e): boolean; // your function
}

Does that help The quick and dirty solution is to cast to any to opt out of type checking i.e.
code :
 onSubmitEditing={(event) => { 
    (this.refs.SecondInput as any).focus(); 
 }}
 type ProperRef = Component <any, any> | HTMLElement

 onSubmitEditing={(event) => { 
    const secondRef =  this.refs.SecondInput as any as ProperRef;
    secondRef.focus(); 
 }}

it fixes the issue Use Module Augmentation to extend existing typings. Create .ts file with the following code
code :
import { BootstrapTableProps, BootstrapTable } from 'react-bootstrap-table';

declare module "react-bootstrap-table" {
  export interface BootstrapTableExProps extends BootstrapTableProps {
    strictSearch?: boolean;
  }

  export interface BootstrapTableEx extends ComponentClass<BootstrapTableExProps> {

  }
}

I hope this helps you . The general idea would be to use a module augmentation, which would look something like this:
code :
declare module "bitbox-javascript-sdk/lib/HDNode" { 
  interface HDNode { 
    createAccount(hdNodes: any): any;
  }
}
