Vue Js Extract Text from Pdf: Vue.js is a JavaScript framework that allows developers to build web applications. To extract text from a PDF using Vue.js, a third-party library can be used. One such library is called “pdf.js,” which provides a set of APIs for working with PDF files in a browser environment.
To extract text from a PDF using pdf.js in a Vue.js application, the PDF file is first loaded using the pdf.js library. Then, the text content of each page can be extracted using the “getTextContent” method provided by pdf.js. The extracted text can be stored in a variable and then displayed or processed as required by the application.
In summary, extracting text from a PDF using Vue.js involves using a third-party library, such as pdf.js, to load and extract text content from a PDF file.
What is the process for extracting text from a PDF file using Vue?
This script uses the Vue.js framework to create an application that can extract text from a PDF file. The application includes a form input where users can upload a PDF file.
When a user selects a file, the onFileChange
method is called. This method checks if the uploaded file is a PDF by checking the file extension. If the file is not a PDF, an alert message is displayed and the method returns.
If the uploaded file is a PDF, the extractTextFromPdf
method is called asynchronously. This method sets the loading property to true before processing the PDF. It uses the pdf.js library to get the number of pages in the PDF, then loops through each page to extract the text content. The extracted text content is stored in an array, and then joined together with newline characters to create a single string of all the extracted text.
Once the text extraction is complete, the extracted text is displayed and the loading property is set to false.
Overall, this script provides a simple and user-friendly way to extract text from a PDF file using Vue.js and pdf.js.
Vue Js Extract Text from Pdf Example
<div id="app">
<div>
<form>
<input type="file" ref="pdfFile" @change="onFileChange">
</form>
<pre v-if="!loading" v-html="extractedText"></pre>
<div v-if="loading">Processing PDF...</div>
</div>
</div>
<script>
new Vue({
el: '#app',
data() {
return {
extractedText: '',
loading: false // add loading property
};
},
methods: {
async extractTextFromPdf(pdfUrl) {
// set loading to true before processing the PDF
this.loading = true;
const pdf = await window.pdfjsLib.getDocument(pdfUrl).promise;
const maxPages = pdf.numPages;
let textContent = [];
for (let i = 1; i <= maxPages; i++) {
const page = await pdf.getPage(i);
const content = await page.getTextContent();
const pageTextContent = content.items.map(item => item.str).join('');
textContent.push(pageTextContent);
}
// set loading to false when the PDF processing is complete
this.loading = false;
return textContent.join('\n');
},
async onFileChange(event) {
const file = event.target.files[0];
const extension = file.name.split('.').pop();
if (extension !== 'pdf') {
alert('Please select a PDF file');
return;
}
const reader = new FileReader();
reader.onload = async () => {
const dataUrl = reader.result;
// set loading to true before extracting text from the PDF
this.loading = true;
const text = await this.extractTextFromPdf(dataUrl);
this.extractedText = text;
// set loading to false when the text extraction is complete
this.loading = false;
};
reader.readAsDataURL(file);
},
},
});
