Recently, I developed an Angular2 application that is capable of generating JSON data. My main goal was to store this JSON output into a file, specifically a PDF file. This project was built using Typescript.
To achieve the functionality of writing JSON data into a PDF file, I utilized jsPDF. The first step involved installing the jsPDF package through npm by executing npm install jspdf --save. Additionally, I included necessary links within the index.html page. While my application was operational, these modifications allowed me to successfully save the JSON data as a PDF file.
However, upon stopping and restarting the application, I encountered an unexpected issue. An error message was displayed:
[email protected] start C:\Users*****\Documents\Projects\Angular\json-to-pdf
tsc && concurrently "npm run tsc:w" "npm run lite"
app/components/app.component.ts(35,19): error TS2304: Cannot find name 'jsPDF'.
I have shared snippets of the code utilized in my project:
package.json:
"dependencies": {
"@angular/common": "2.0.0-rc.1",
// Additional dependencies...
"jspdf": "^1.2.61",
// More dependencies...
}
index.html:
<html>
<head>
<title>JSON to PDF</title>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
....
<script src="https://cdnjs.cloudflare.com/ajax/libs/jspdf/1.0.272/jspdf.debug.js"></script>
....
</head>
// Remaining HTML structure...
app.component.ts:
import {Component} from '@angular/core';
@Component({
// Component details...
})
export class AppComponent {
public item = {
"Name" : "XYZ",
"Age" : "22",
"Gender" : "Male"
}
constructor() {}
createFile(){
var doc = new jsPDF();
var i=0;
for(var key in this.item){
doc.text(20, 10 + i, key + ": " + this.item[key]);
i+=10;
}
doc.save('Test.pdf');
}
}
It appears that there might be an issue with the import statement within the app.component.ts file. Could someone kindly assist in identifying the correct import statement? If the absence of the import statement caused this error, I would appreciate guidance on how to precisely utilize jsPDF in Angular2.
Your support is greatly appreciated.
