# Installing Node

Node.js is required for several Titanium SDK components, including the Titanium CLI and Alloy.

# Compatibility and download

Titanium supports and recommends the latest Node.js LTS release.

Check Titanium Compatibility Matrix which version of Node.js is required for each Titanium SDK version.

# Using NPM packages in Titanium

  1. Run npm init in the app/lib folder in your Alloy project. If you are using a classic app, run the init step in your /Resources folder.

  2. Follow the steps npm gives you when doing the init step. Note: You don’t have to fill out anything if you don't need to.

  3. Execute npm i <packagename> in the /lib folder to install a package. For example, let’s set up to.imagecache (opens new window). You'd use this comment to install the package: npm i to.imagecache

  4. Add the lib/node_modules folder and the package-lock.json file to your .gitignore folder.

  5. On any other machine you want to set this up, go to your /lib folder, run npm install and all packages will be installed to your app.

# Usage of packages

Usage of a package is like another module or library file. Using the to.imagecache example:

var imageCache = require('to.imagecache');

# Dependencies

To install a package dependency,

  1. Ensure you are in the /lib folder, or if using a classic project, the /Resources folder.

  2. Execute npm i <dependency>

  3. To use the dependency, for example a module called ImageView from the to.cacheimageview (sample extension of the to.imagecache package):

    <ImageView id="myImage" module="to.cachedimageview" />
    

# Finding packages

To find all the current packages with the titanium-module, you can use this npm site search: https://www.npmjs.com/search?q=keywords:titanium-module (opens new window)

A lot of Titanium packages are found using the titanium or titanium-module keywords. Note: when creating a public common.js module and/or library file, please tag it with the titanium-module keyword.

# Troubleshooting

# Error: EONT, stat C:\Users\<USER_NAME>\AppData\Roaming\npm

The error message indicates the folder is missing. To resolve this issue, manually create the folder:

mkdir C:\Users\<USER_NAME>\AppData\Roaming\npm

# Issues installing NPM packages

If you experience an issue installing any of the npm packages, try the following:

  • Check permissions. If you originally ran npm using sudo, you may need to change the ownership of the npm cache folder.

    sudo chown -R <username> ~/.npmrc
    

    On Windows, the npm cache defaults to npm-cache in the user's home folder.

  • Clear the npm package cache:

    npm cache clean
    
  • Remove your .npmrc file.
