Javascript Library for Merging Docx file in NodeJS and Browser Environment.
To merge docx file using javascript which has rich contents.
The Library Preserves the Styles, Tables, Images, Bullets and Numberings of input files.
npm install docx-mergerRead input files as binary and pass it to the DocxMerger constructor fuction as a array of files.
Then call the save function with first argument as nodebuffer, check the example below.
var DocxMerger = require('docx-merger');
var fs = require('fs');
var path = require('path');
var file1 = fs
.readFileSync(path.resolve(__dirname, 'template.docx'), 'binary');
var file2 = fs
.readFileSync(path.resolve(__dirname, 'template1.docx'), 'binary');
var docx = new DocxMerger({},[file1,file2]);
//SAVING THE DOCX FILE
docx.save('nodebuffer',function (data) {
// fs.writeFile("output.zip", data, function(err){/*...*/});
fs.writeFile("output.docx", data, function(err){/*...*/});
});- Async Load files using
jszip-utilsand then call the callback in the innermost callback. - Call the save function wit first argument as
blob. - Better use Promises instead of callbacks.
- Callback causes callback hell issue.
