node-odt

A node js tool to work with OpenDocument text files.

Install

  $ npm install odt

Usage

var fs = require('fs')
  , odt = require('odt')
  , template = odt.template
  , createWriteStream = fs.createWriteStream
var doc = 'mytemplate.ott';
var values = {
  'subject': { type: 'string', value: 'My subject value' }
};
 
// apply values
 
template(doc)
  .apply(values)
  .on('error', function(err){
    throw err;
  })
  .on('end', function(doc){
 
    // write archive to disk.
 
    doc.pipe(createWriteStream('mydocument.odt'))
    doc.finalize(function(err){
      if (err) throw err;
      console.log('document written!');
    });
  });

This example can be written much easier using the convenience methods pipe() and finalize().

var fs = require('fs')
  , odt = require('odt')
  , template = odt.template
  , createWriteStream = fs.createWriteStream
var doc = 'mytemplate.ott';
var values = { 'subject': 'My subject value' };
 
// apply values
 
template(doc)
  .apply(values)
  .on('error', function(err){
    throw err;
  })
  .finalize(function(bytes){
    console.log('The document is ' + bytes + ' bytes large.');
  })
  .pipe(createWriteStream('mydocument.odt'))
  .on('close', function(){
    console.log('document written');
  });

For a more advanced example see the command line utility in bin/node-odt.

API

Template(arg : String|Stream)

The main class to work with templates. arg can be a path to the odt file or a stream with the odt contents. Template inherits from EventEmitter and fires the following events:

events

• error - Fired if an error occurs.
• end(document) - Fired when the document is complete.

.apply(values : Object)

Applies the values to the template. values is an object of the following form:

{
  "field-name": {
    "type": "field-type",
    "value": "field-value"
  }
}

e.g.

{
  "subject": {
    "type": "string",
    "value": "My subject"
  },
  ...
}

Supported data types

• string - This type is well supported and does what you think.
• date - This type can be either an unix timestamp (Number) or a javascript Date.
• cent - This type should have an integer as value which is converted into a float representing the Euro currency.

.apply(handler : Function)

Registers a handler to modify the content. handler is a function of the form function(content, done) while content is the parsed xml data of the content.xml file in the document archive. done is a function which needs to be called upon completion.

.pipe(stream : Stream)

Pipes the archive to stream.

.finalize(done : Function)

Register a handler on the 'finalized' event. This was formerly needed to launch the finalization of the archive. But this is done automatically now.

Bundled handlers

Table handler

This handler applies a table template to a table defined by libreoffice.

Warning: This part of the code is yet pretty unstable and might be changed in future. Use it carefully.

Usage

var odt = require('odt')
  , table = require('odt/handler').table;
odt
  .template('mytemplate.ott')
  .apply(
    table({
      Table1: {
        'subject': { ... },
        ...
      }
    })
  )
  ...
