Eclipse Theia Blueprint is an example product used as a reference on how to build desktop IDE-like products based on the Eclipse Theia framework.Theia Blueprint assembles a selected subset of existing Theia features and extensions.We provide installers for Theia Blueprint to be downloaded (see links below).In the respective git repository you can also find the source code for Theia Blueprint and its installers.This documentation will use these sources as a template. We will explainhow to customize this template so you can build your own custom Theia-based product including installers and packaging for installing the desktop-based version of your custom product on all major operating systems.

  • Cloud & Desktop IDE Framework Eclipse Theia is an extensible framework to develop full-fledged multi-language Cloud & Desktop IDE-like products with state-of-the-art web technologies. Theia 1.0 has been released.
  • Theia provides the end-user with a full-fledged multi-language IDE (not just a smart editor) and supports equally the paradigm of Cloud IDE and Desktop IDE. Cloud9 IDE and Theia belong to 'Cloud IDE' category of the tech stack. Theia is an open source tool with 4.66K GitHub stars and 584 GitHub forks.
  • Gitpod streamlines developer workflows by providing prebuilt, collaborative development environments in your browser - powered by VS Code.

Building a product and installers

The Theia Blueprint build uses electron-builder to package the product as a desktop application.

The product can be built and packaged with yarn.Note that you usually can only package the product for the operating system you execute the build on.For more information see the electron-builder documentation on multi platform builds.

The following commands may be run from the root directory of the repository.

To install dependencies and build the application, simply execute yarn.

You can also directly run the unpackaged application, e.g. to test it during development with yarn start.

With yarn package, you package the application into an executable file for your current operating system.The packaged application will be located in electron-app/dist.The folder electron-app/dist/<OS>-unpackaged will contain the files that are bundled into the final packaged executable.For Linux, this is an executable .AppImage, for Windows a .exe installer, and a .pkg installer for macOS.

You can also just create the unpackaged content by running yarn package:preview.This is useful to see the bundled files and saves time compared to a full package.To publish the current version, the command yarn deploy can be used.For more information on publishing also see section 'Configure publish and update'.


Electron-builder supports signing the packaged application on Windows and macOS.The current signing scripts for Theia Blueprint are located in electron-app/scripts.The file after-pack.js is the current entry point for the configured signing via Eclipse infrastructure.

However, as signing is highly dependent on your setup, see the electron builder’s signing documentation on how to properly set up your own signing.

Updating Bundled VS Code Extensions

All VS Code extensions that are already included in the product at start-up, are defined in electron-app/package.json.They are listed under the theiaPlugins property as key-value pairs.The keys can be freely chosen as long as they represent a valid folder name and are unique within the theiaPlugins property.We suggest using the extension’s unique identifier.The value is the download URL of the extensions.It will automatically be downloaded during the application’s build process.Any new plugin will be automatically downloaded the next time one of the following npm scripts is executed:

  • install (which is the same as just running yarn)
  • prepare
  • download:plugins

To remove an extension from the product, simply delete its entry.If plugins were not already downloaded, no further steps are required as downloaded plugins are ignored via gitignore.However, previously downloaded plugins are not automatically removed.Therefore, you need to remove its folder from the electron-app/plugins folder.Alternatively, you can remove the whole electron-app/plugins folder and execute yarn run download:plugins to download all defined plugins.

Extension sources

We use the Open VSX Registry of the Eclipse Foundation to install extensions.It is an open and community-driven VS Code extension marketplace.More information can be found at

Customizing Theia Extensions

Eclipse Theia extensions can be added through dependencies in electron-app/package.json.Like any other dependency, it will be installed via yarn.Similarly, removing an extension works by removing it from dependencies.For extensions already published on npm (or your private npm registry) this is all you need to do.

An alternative approach is developing your extension inside Theia Blueprint’s mono repo.The advantage of doing this is that you don’t need to publish the extension and can build the product with the local version of the extension.This is facilitated by the lerna build already configured in the Theia Blueprint’s repository.It links the product and all extensions in the repository together during the build.

The easiest way to create a new extension is to use the official yeoman generator for Theia extensions.Assuming you have yeoman globally installed on your system, simply create a new extension in the repository root with yo theia-extension --standalone.The --standalone flag is used to only create an extension but not a whole Theia application frame because it is already provided by the Theia Blueprint.After successfully generating the extension, add its folder name to the Theia Blueprint’s root package.json in the workspaces property.After adding the extension to the dependencies in electron-app/package.json as described above, the new extension will be part of the built product.



You can also add your own branding to the product by customizing the application icons and title, the welcome page and the About dialog.In addition, some parts of the installer can be customized.

Customizing the App


Application Window Title

The window title is the application’s name if no workspace is opened and <workspace name> — <application name> if a workspace is opened.The application name can be adapted in electron-app/package.json:Open the file and adapt the value of property theia.frontend.config.applicationName to the desired name.

Application Icons

Application icons are located in electron-app/resources/.Simply replace them with your own icons.Because each operating system handles icons differently, they should all be replaced to ensure proper use.They map as follows:

Theia Cloud Identifier

  • macOS: icons.icns
  • Windows: icon.ico
  • Linux: icons subfolder

Customizing the Welcome Page

The Eclipse Theia welcome page can be customized by binding a custom WidgetFactory for Theia’s GettingStartedWidget.This is done with Theia Blueprint in the theia-blueprint-product extension.The easiest way to customize the welcome page is to adapt the class TheiaBlueprintGettingStartedWidget in theia-blueprint-product/src/browser/theia-blueprint-getting-started-widget.tsx.

The widget is bound in theia-blueprint-product/src/browser/theia-blueprint-frontend-module.ts like this:

To use another custom widget, remove this code and bind your widget correspondingly.

Customizing the About Dialog

The Eclipse Theia about dialog can be customized by binding a custom subclass of Theia’s AboutDialog class to AboutDialog.This is done with Theia Blueprint in the theia-blueprint-product extension.The easiest way to customize the about dialog is to adapt the class TheiaBlueprintAboutDialog in theia-blueprint-product/src/browser/theia-blueprint-about-dialog.tsx.

The widget is bound in theia-blueprint-product/src/browser/theia-blueprint-frontend-module.ts like this:

To use another custom dialog widget, remove this code, extend Theia’s AboutDialog class, and (re)bind it as above.

Customizing the Installer

The installers are created using electron-builder.The corresponding configuration file is located at electron-app/electron-builder.yml.

Installer File Base Name


The installer files’ base names are defined by the productName property in electron-app/electron-builder.yml.

Windows Installer

As is typical for Windows applications, there is an installation wizard for the Windows version of Theia Blueprint.The installer is configured in the nsis section of the configuration file.Available customizations include settings such as:

More details on available options and how they can be customized can be found in the official electron builder documentation.This documentation also includes information about more advanced features such as custom NSIS scripts.

Configure Publish and Update

Theia Cloud Identity

Theia Blueprint uses electron-builder to create and publish installers.It also uses electron-updater, developed by the electron-builder organization, to provide automatic updates of the installed application.

Cloud 9 Html Editor

There are various deployment targets which can be configured in the electron-app/package.json and electron-app/electron-builder.yml as documented here in the Electron Builder documentation.Multiple publish configurations can be configured.Thereby, the first one is automatically used by the updater to look for available updates.The currently used generic publishing method does not automatically publish to the specified server, but is just used as the lookup location for the updater.
