打字稿：如何在node_modules中导入和添加嵌套文件的输入？

Question

installed with:

npm install highcharts
typings install highcharts/highstock --ambient

index.ts:

import * as Highstock from 'highcharts/highstock'
new Highstock() // Cannot use 'new' with an expression whose type lacks a call or construct signature.

tsconfig.json:

{
  "compilerOptions": {
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "moduleResolution": "node",
    "noEmitHelpers": true,
    "outFile": "./dist/index.js",
    "preserveConstEnums": true,
    "target": "es6"
  },
  "files": [
    "typings/browser.d.ts",
    "ty.d.ts",
    "src/index.ts"
  ]
}

Answer 1

for anyone that finds this question in the future, i needed to wrap the highcharts typings like so:

declare module 'highcharts/highstock' {
  // typings go here
}

i assume there's some way to re-export the community typings from inside this declared module, but for now i'm manually adding typings as i go.

Answer 2

new Highstock() // Cannot use 'new' with an expression whose type lacks a call or construct signature.

TypeScript definitions for JavaScript libraries are best effort (ie might not be up to date). That definition file ( https://github.com/DefinitelyTyped/DefinitelyTyped/blob/master/highcharts/highstock.d.ts ) does not support such usage. If that is a usage that should be supported feel free to create a Github Pull Request 🌹
