Snap PDF is a powerful tool for programmatic generation of high-quality PDFs from a variety of sources. With Snap PDF, programmers can easily generate professional-looking PDFs with a few lines of code.
To get started with Snap PDF, install the package using npm:
npm install snap-pdf
Once installed, import the library and initialize it with your desired options:
const SnapPDF = require('snap-pdf');
const options = {
font: 'Arial',
fontsize: '12pt',
margin: '1in',
};
const snapPDF = new SnapPDF(options);
With Snap PDF initialized, you can now use it to generate PDFs from various sources:
const html = '<h1>Hello, world!</h1>';
async function generatePDF() {
const pdfBuffer = await snapPDF.fromHtml(html);
// do something with pdfBuffer
}
const imagePath = '/path/to/image.png';
async function generatePDF() {
const pdfBuffer = await snapPDF.fromImage(imagePath);
// do something with pdfBuffer
}
const code = 'console.log("Hello, world!");';
async function generatePDF() {
const pdfBuffer = await snapPDF.fromCode(code);
// do something with pdfBuffer
}
Snap PDF allows you to customize various aspects of your PDF output, including fonts, colors, and page sizes.
To change the default font used in your PDF:
const options = {
font: 'Helvetica',
};
const snapPDF = new SnapPDF(options);
To change the default text and background colors used in your PDF:
const options = {
textColor: '#333333',
backgroundColor: '#f5f5f5',
};
const snapPDF = new SnapPDF(options);
To change the default page size and margins used in your PDF:
const options = {
pageSize: 'A4',
margin: '0.5in',
};
const snapPDF = new SnapPDF(options);
Snap PDF is a powerful tool for creating high-quality PDFs programmatically. With its support for multiple sources and advanced layout features, you can create professional-looking documents quickly and easily.
