Combine HTML to PDF using JavaScript REST API

Easily merge HTML to PDF format in JavaScript code. This JavaScript library is designed to combine multiple HTML files into a single PDF file using the REST API, i.e. by passing HTTPS calls over the Internet.

This is a professional Cloud-native HTML to PDF merging solution that provides JavaScript programmers with both great development flexibility and powerful features. Joining HTML files together is often used when it is necessary to create a set of PDF documents of the same structure, each of which contains unique data. By merging files, you can automate your digital HTML/PDF workflows and offload some routine parts of the process to fast and efficient document-processing JavaScript software.

Merge several HTML into one PDF in JavaScript

You may need to combine HTML files into a single PDF file in many cases. For example, you may want to combine multiple HTML files together before printing or archiving.

HTML merging can be part of a whole integrated document-processing approach for generating PDF documents from disparate data sources. Such tasks involve the use of a full-featured HTML/PDF manipulation JavaScript library that will process a set of HTML files and merge them together in the shortest possible time, producing a compact and accurate PDF result.

Merge HTML to PDF in JavaScript

To perform HTML to PDF merging in JavaScript, you need at least two source HTML files. For a quick start, please check out the JavaScript code example below.

const wordsApi = new WordsApi("####-####-####-####-####", "##################");

const document = fs.createReadStream("Input1.html");
// Load a document to append from the Cloud storage.
const mergeDocument = new model.DocumentEntry({
    fileReference: model.FileReference.fromRemoteFilePath("Input2.html"),
    importFormatMode: "KeepSourceFormatting"
})

const documentEntries = [ mergeDocument ]
const documentList = new model.DocumentEntryList({
    documentEntries: documentEntries
})

const appendDocumentOnline = new model.AppendDocumentOnlineRequest({
    document: document,
    documentList: documentList
});
wordsApi.appendDocumentOnline(appendDocumentOnline)
.then((appendDocumentOnlineResult) => {
    console.log("Result of AppendDocumentOnline: ", appendDocumentOnlineResult);
});
