## Usage
This documentation will guide you through using `@push.rocks/smartpdf` to create PDFs in various ways, such as from HTML strings or full web pages, and provides examples on how to merge multiple PDFs into one. Remember, all examples provided here use ESM syntax and TypeScript.
## Contribution
### Getting Started
First, ensure you have the package installed and you can import it into your TypeScript project:
We are always happy for code contributions. If you are not the code contributing type that is ok. Still, maintaining Open Source repositories takes considerable time and thought. If you like the quality of what we do and our modules are useful to you we would appreciate a little monthly contribution: You can [contribute one time](https://lossless.link/contribute-onetime) or [contribute monthly](https://lossless.link/contribute). :)
```typescript
import { SmartPdf, IPdf } from '@push.rocks/smartpdf';
```
## Contribution
### Creating a PDF from an HTML String
To create a PDF from a simple HTML string, youll need to instantiate `SmartPdf` and call `getA4PdfResultForHtmlString`.
We are always happy for code contributions. If you are not the code contributing type that is ok. Still, maintaining Open Source repositories takes considerable time and thought. If you like the quality of what we do and our modules are useful to you we would appreciate a little monthly contribution: You can [contribute one time](https://lossless.link/contribute-onetime) or [contribute monthly](https://lossless.link/contribute). :)
```typescript
async function createPdfFromHtml() {
const smartPdf = await SmartPdf.create();
await smartPdf.start();
const htmlString = `<h1>Hello World</h1>`;
const pdf: IPdf = await smartPdf.getA4PdfResultForHtmlString(htmlString);
console.log(pdf.buffer); // This is your PDF buffer
await smartPdf.stop();
}
createPdfFromHtml();
```
For further information read the linked docs at the top of this readme.
### Generating a PDF from a Website
You may want to capture a full webpage as a PDF. `SmartPdf` provides two methods to accomplish this. One captures the viewable area as an A4 pdf, and the other captures the entire webpage.

#### A4 PDF from a Website
[![repo-footer](https://lossless.gitlab.io/publicrelations/repofooter.svg)](https://maintainedby.lossless.com)
```typescript
async function createA4PdfFromWebsite() {
const smartPdf = await SmartPdf.create();
await smartPdf.start();
const pdf: IPdf = await smartPdf.getPdfResultForWebsite('https://example.com');
console.log(pdf.buffer); // PDF buffer of the webpage
await smartPdf.stop();
}
createA4PdfFromWebsite();
```
#### Full Webpage as a Single PDF
```typescript
async function createFullPdfFromWebsite() {
const smartPdf = await SmartPdf.create();
await smartPdf.start();
const pdf: IPdf = await smartPdf.getFullWebsiteAsSinglePdf('https://example.com');
console.log(pdf.buffer); // PDF buffer with the full webpage
await smartPdf.stop();
}
createFullPdfFromWebsite();
```
### Merging Multiple PDFs
If you have multiple PDF objects (`IPdf`) that you wish to merge into a single PDF file, you can use the `mergePdfs` method.
```typescript
async function mergePdfs() {
const smartPdf = await SmartPdf.create();
// Assume pdf1 and pdf2 are objects of type IPdf that you want to merge
const mergedPdf: IPdf = await smartPdf.mergePdfs([pdf1, pdf2]);
console.log(mergedPdf.buffer); // Buffer of the merged PDF
}
mergePdfs();
```
### Reading PDF from Disk and Extracting Text
To read a PDF from the disk and extract its text content:
```typescript
async function readAndExtractFromPdf() {
const smartPdf = await SmartPdf.create();
const pdf: IPdf = await smartPdf.readFileToPdfObject('/path/to/your/pdf/file.pdf');
const extractedText = await smartPdf.extractTextFromPdfBuffer(pdf.buffer);
console.log(extractedText); // Extracted text from the PDF
}
readAndExtractFromPdf();
```
This guide provides a comprehensive overview of generating PDFs using `@push.rocks/smartpdf`. Remember to start and stop your `SmartPdf` instance to properly initialize and clean up resources, especially when working with server-side rendering or capturing web pages.
