I can’t seem to get azure-devops-node-api working. I tried to create a minimal example:

Start new..

  1. npm init
  2. npm install —save-dev typescript
  3. npm install —save azure-devops-node-api
  4. create index.ts like so: 
    import * as azdev from "azure-devops-node-api";

// your collection url
let orgUrl = "https://dev.azure.com/yourorgname";

// ideally from config
let token: string = "cbdeb34vzyuk5l4gxc4qfczn3lko3avfkfqyb47etahq6axpcqha"; 

let authHandler = azdev.getPersonalAccessTokenHandler(token); 
let connection = new azdev.WebApi(orgUrl, authHandler);

running tsc yields:

> test1@1.0.0 build D:_devtest1

Node.js Setup:This may indicate a problem with this package. The error code is 2503.

Недавно из-за причин стажировки (в частности, потому что бакалавры введены в эксплуатацию, чтобы есть память и ЦП, моя низкая оборудованная скорость RMBP немного медленная), чтобы мигрировать на разработку Windows 10.

Самым большим преимуществом является 4 ГГц CPU, 32G память, а стоимость — это определенная стоимость адаптации. Когда я установил Node.js, я соответствовал следующему вопросу:

Советы по ошибкам не очевидны, но общие причины недостаточно.

Метод 1.

Обходной путь — это установщик Windows для запуска Node.js под привилегиями PowerShell из администратора.

Вышеуказанный путь определяется в соответствии с вашим индигром, а затем его должно быть успешно установлено:

Installing typings should resolve this. [. ]

However, the project comes with it’s own typings.. So I am unsure which typings to install.

Issue

I was try to export an excel file using ExcelJS

Here is my console in VS Code terminal :

import { Component } from '@angular/core';
import * as Excel from 'exceljs';

@Component({

    const workbook = new Excel.Workbook();
    const worksheet = workbook.addWorksheet('My Sheet');

    worksheet.columns = [
      { header: 'Id', key: 'id', width: 10 },
      { header: 'Name', key: 'name', width: 32 },
      { header: 'D.O.B.', key: 'dob', width: 15, }
    ];

    worksheet.addRow({ id: 1, name: 'John Doe', dob: new Date(1970, 1, 1) });
    worksheet.addRow({ id: 2, name: 'Jane Doe', dob: new Date(1965, 1, 7) });

    // save under export.xlsx
    await workbook.xlsx.writeFile('export.xlsx');

    // load a copy of export.xlsx
    const newWorkbook = new Excel.Workbook();
    await newWorkbook.xlsx.readFile('export.xlsx');

    const newworksheet = newWorkbook.getWorksheet('My Sheet');
    newworksheet.columns = [
      { header: 'Id', key: 'id', width: 10 },
      { header: 'Name', key: 'name', width: 32 },
      { header: 'D.O.B.', key: 'dob', width: 15, }
    ];
    await newworksheet.addRow({ id: 3, name: 'New Guy', dob: new Date(2000, 1, 1) });

    await newWorkbook.xlsx.writeFile('export2.xlsx');

    console.log('File is written');
  }
}

I don’t get it why it is looking for stream module (and more funny thing — Cannot find namespace ‘NodeJS’ — I can run all other angular NodeJS projects without error)

Please point out why i can’t export excel.

Solution

You can’t write directly a file on client side. that method is mean to be used on backend side in nodejs. if your expectation is download this file on client side. your code should be like :- 

import { Component } from "@angular/core";
import * as Excel from "exceljs";
@Component({
  selector: "my-app",
  templateUrl: "./app.component.html",
  styleUrls: ["./app.component.css"]
})
export class AppComponent {
  title = "resttest10";

  async downloadExcel() {
    const date = new Date()
      .toISOString()
      .slice(0, 10)
      .split("-")
      .reverse()
      .join("/");
    console.log(date);
    const workbook = new Excel.Workbook();
    const worksheet = workbook.addWorksheet("My Sheet");

    worksheet.columns = [
      { header: "Id", key: "id", width: 10 },
      { header: "Name", key: "name", width: 32 },
      { header: "D.O.B.", key: "dob", width: 15 }
    ];

    worksheet.addRow({ id: 1, name: "John Doe", dob: new Date(1970, 1, 1) });
    worksheet.addRow({ id: 2, name: "Jane Doe", dob: new Date(1965, 1, 7) });

    workbook.xlsx.writeBuffer().then((data: any) => {
      console.log("buffer");
      const blob = new Blob([data], {
        type:
          "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"
      });
      let url = window.URL.createObjectURL(blob);
      let a = document.createElement("a");
      document.body.appendChild(a);
      a.setAttribute("style", "display: none");
      a.href = url;
      a.download = "export.xlsx";
      a.click();
      window.URL.revokeObjectURL(url);
      a.remove();
    });
  }
}
