Create Word Document inside Node.js Apps

Aspose.Words Cloud SDK for Node.js has provided complete functionality that allows software developers to programmatically create a new word document and add contents to it inside their own Node.js applications. After the creation of document developers can easily add text, images, shapes, manage fonts, define styles and formatting, manage page size, insert tables and charts, add headers/footers and so on. Here is a simple example that shows how software developers can create a new word document inside Node.js applications.

 import * as fs from "fs";

const clientId = "####-####-####-####-####";
const secret = "##################";
const wordsApi = new WordsApi(clientId, secret);
const createRequest = new model.CreateDocumentRequest({
fileName: "Sample.docx"
});

wordsApi.createDocument(createRequest)
.then((createRequestResult) => {
// tslint:disable-next-line:no-console
console.log("Result of createRequest: ", createRequestResult);
});

Word Document Conversion via Node.js SDK

Software developers can use Aspose.Words Cloud SDK for Node.js, to convert MS Word documents from one format to another with just a couple of lines of code inside their own applications. Whether you need to convert DOCX to PDF, HTML to DOC, or any other combination, the SDK provides simple methods to accomplish these tasks efficiently. The following example demonstrates how software developers can convert word DOCX file to PDF inside Node.js environment.

 
// create API instance (baseUrl is optional)
        const wordsApi = new WordsApi(clientId, clientSecret, baseUrl);

        // upload file to the Aspose cloud
        const uploadRequest = new UploadFileRequest();
        uploadRequest.path = "uploaded.docx";
        uploadRequest.fileContent = createReadStream(localPath);

        wordsApi.uploadFile(uploadRequest)
            .then((_uploadResult) => {
                // save the file as pdf in the cloud
                const request = new SaveAsRequest({
                    name: "uploaded.docx",
                    saveOptionsData: new PdfSaveOptionsData(
                        {
                            fileName: "destination.pdf"
                        })
                });

                wordsApi.saveAs(request)
                    .then((_result) => {
                        // deal with the pdf file
                    })
                    .catch(function(_err) {
                        // handle saveAs request error
                    });
            })
            .catch(function(_err) {
                // handle uploadFile request error
            });

Extract Text from Word Documents via Node.js

Extracting text as well as images from various types of documents is a common requirement in many applications, such as text analysis or content indexing and so on. Aspose.Words Cloud SDK for Node.js offers seamless text extraction capabilities, allowing software developers to retrieve text content with ease. The SDK also provides useful methods for extracting logos, illustrations, or photographs embedded within the document. Here's an example that shows how users can extract text from a DOCX document inside Node.js.

const { WordsApi, GetDocumentTextRequest } = require("asposewordscloud");

// Initialize Words API
const wordsApi = new WordsApi();

// Extract text from DOCX
const getTextRequest = new GetDocumentTextRequest({
  name: "input.docx",
});

wordsApi.getDocumentText(getTextRequest)
  .then((result) => {
    console.log("Text extracted:", result.text);
  })
  .catch((error) => {
    console.error("Error extracting text:", error);
  });

Apply Mail Merge in Node.js

What sets Aspose.Words Cloud SDK apart is its intuitive API design, which allows software developers to perform complex tasks with just a few lines of code. The SDK simplifies the process of generating personalized documents using mail merge functionality inside Node.js applications. Software developers can easily populate document templates with data from external sources, such as databases or JSON files, to create customized documents in bulk. Here's an example of performing a mail merge with a JSON data source. 

const { WordsApi, ExecuteMailMergeOnlineRequest, MailMergeData } = require("asposewordscloud");

// Initialize Words API
const wordsApi = new WordsApi();

// Perform mail merge with JSON data
const mailMergeData = new MailMergeData();
mailMergeData.dataSourceType = "json";
mailMergeData.dataSource = fs.createReadStream("data.json");

const executeMailMergeRequest = new ExecuteMailMergeOnlineRequest({
  template: fs.createReadStream("template.docx"),
  data: mailMergeData,
});

wordsApi.executeMailMergeOnline(executeMailMergeRequest)
  .then((result) => {
    console.log("Mail merge completed. Merged document saved.");
  })
  .catch((error) => {
    console.error("Error performing mail merge:", error);
  });
