When I tried to use exceljs
in Angular-6
like so
import * as excel from 'exceljs'
createExcel() {
let workbook = new excel.Workbook()
}
even I just initialize a class and got this error. If I comment out this line let workbook = new excel.Workbook()
then error gone
./node_modules/fs-constants/browser.js Module not found: Error: Can't resolve 'constants' in 'D:\Developer\spire-client\node_modules\fs-constants'
You could import it as follow
import * as Excel from 'exceljs';
after that, you can use Exceljs:
const myWorkbook = new Excel.Workbook()
or
import * as Excel from "exceljs/dist/exceljs.min.js";
import * as ExcelProper from "exceljs";
let workbook: ExcelProper.Workbook = new Excel.Workbook();
As long as you just use the import from exceljs for type definitions and only use functions from the import from exceljs/dist/exceljs.min.js, the app will run just fine and you still get type safety.
