Eclipse Theia is a free and open-source integrated development environment (IDE) framework for desktop and web applications. It is implemented in TypeScript, is based on Visual Studio Code, and emphasizes extensibility. Eclipse Theia produces an extensible platform for developing browser and desktop IDEs. In particular, the following is supported: Use Theia as a basis for IDE-like products. Provide the end-user with a full-fledged, multi-language IDE (not just a smart editor). Support equally the paradigm of Cloud IDE and Desktop IDE. Theia is designed in a modular way to allow extenders and adopters customizing and extending every aspect of it. Composing a custom IDE-like product is as easy as listing all needed extensions in a package.json file. Adding new functionality by implementing your own extensions is easy, too and provides all the flexibility you need. Eclipse Theia is a framework for building a fully customized, single-source IDE that runs in web browsers and as a native desktop application. It combines the design ideas and ecosystem from the Microsoft Visual Studio Code IDE with the flexibility and customization capabilities from the Eclipse IDE so it offers the best of both worlds.
A Single IDE for Cloud and Desktop Deployments
As the first official release of Eclipse Theia approaches, Project Lead, Sven Efftinge, explains why so many companies — big and small — are using this extensible, multi-language platform to develop all-in-one cloud and desktop IDEs.
Q. What exactly is Eclipse Theia?
A. Eclipse Theia is a framework for building a fully customized, single-source IDE that runs in web browsers and as a native desktop application. It combines the design ideas and ecosystem from the Microsoft Visual Studio Code IDE with the flexibility and customization capabilities from the Eclipse IDE so it offers the best of both worlds. Plus, it runs in a browser.
Q. Why is it important that Eclipse Theia supports cloud and desktop IDE development?
A. Traditionally, IDEs run as a native app in a desktop operating system. But, more and more of the applications developers use, from email to spreadsheets to text documents, are in the cloud and accessed through browsers. The IDE is one of the last remaining desktop applications developers use.
For years now, companies have been thinking about how they can move to an IDE with a fresh technology stack and cloud-based development tools. But, from a strategic perspective, it’s often difficult for them to determine whether they should invest in redeveloping their desktop IDE for the web. The same is true if they started with a cloud IDE, but now need desktop development capabilities.
With Eclipse Theia, companies are freed from having to make these difficult decisions. They can develop a modern IDE once then deploy it in both cloud and desktop development environments.
Eve online vedmak. Q. Who are some of the companies that are using the Theia technology?
A. Right from the beginning, major, global companies recognized the value that Theia provides. In fact, Ericsson was one of our first contributors — even before the project was part of the Eclipse Foundation — and they’re still one of our top contributors.
Today, a number of very prominent companies use Theia as the basis for their IDEs, including:
- Arm and Arduino, who are using Theia to write embedded code
- Google, who is using Theia in its Google Cloud shell
- IBM, who is using Theia for multiple projects
- Red Hat, who has replaced its Java-based IDE with Theia as part of the Eclipse Che project
- SAP, who has replaced its existing web IDE with Theia
We’re also seeing a lot of engagement and adoption among smaller businesses and startups, and across industries — from hardware design to aerospace, insurance, and finance.
Theia really is ideal for all companies of all sizes in all industries.
Q. Why do you think companies that have traditionally used in-house or proprietary IDEs are moving to Eclipse Theia, which is open source?
A. Companies want to ensure that when they invest in an IDE, no single vendor is controlling the future or scope of it. Projects at the Eclipse Foundation are guaranteed to be completely vendor-neutral.
They also want to leverage the contributions of a diverse and engaged community. Eclipse Theia has 125 contributors so the project is very active and continually advancing.
Companies that use Theia gain all the advantages of a truly open source IDE, and they have the flexibility to easily customize the platform for their own development requirements.
Q. What makes Eclipse Theia so easy to customize?
A. From an architectural perspective, the project consists of many small extensions that work together. You can pick the extensions you want to include and skip those you don’t want to include. You can also write your own extensions.
In addition, you can modify the functionality and the user interface at a very fine-grained level using libraries. There’s no need to patch or fork the core code.
Q. Why is this flexibility important?
A. The architectural flexibility makes it easy to build an IDE that’s aligned with business goals and developer requirements.
For example, one goal might be to minimize the onboarding time and learning curve for developers migrating to the new IDE. Another might be to provide access to more advanced development tools. We helped Arduino tailor the user interface and user experience so it’s very similar to their legacy IDE, “hiding” more advanced capabilities behind a button. These types of approaches are particularly helpful for companies that need to migrate a large developer base to the new IDE.
Theia is also very flexible from a programming perspective. It natively supports Visual Studio Code extensions, and there are more than 15,000 of them in the marketplace. That means developers can use just about any programming language in a Theia-based IDE.
Q. Is it hard to contribute to Eclipse Theia?
A. No, it’s super-easy. There’s no long readme about how to set up your computer, the compilers you need, or the tools that are required. You just click one button and you can start coding.
You can create a workspace using Gitpod.io, our professional hosting solution for Theia. In just a few seconds, it gives you a fully built Theia code base you can use to contribute changes to the project.
We see this simplicity as one of the reasons we have so many high-quality contributions. The project has a star rating of almost 7,000 on GitHub so developers obviously like what we’re doing.
Q. What are the upcoming plans for Eclipse Theia?
A. War thunder cv90105. We’re focusing on being 100 percent compatible with all Visual Studio Code extensions. Right now, we support about 90 percent of them so we’re working on the last 10 percent.
And, we’re targeting a Theia 1.0 release on March 26.
Longer term, we’ll be focusing on strengthening all of the aspects associated with a mature, production-ready platform — robustness, speed, reliable performance, and APIs.
Q. How can people get involved in Eclipse Theia?
A. We have weekly developer meetings and we welcome everyone who is interested to join the calls.

Introduction
With developer tools moving to the cloud, adoption of cloud IDE (Integrated Development Environment) platforms is growing. Cloud IDEs are accessible from every type of modern device through web browsers, and they offer numerous advantages for real-time collaboration scenarios. Working in a cloud IDE provides a unified development and testing environment for you and your team, while minimizing platform incompatibilities. Accessible through web browsers, cloud IDEs are available from every type of modern device.
Eclipse Theia is an extensible cloud IDE running on a remote server and accessible from a web browser. Visually, it’s designed to look and behave similarly to Microsoft Visual Studio Code, which means that it supports many programming languages, has a flexible layout, and has an integrated terminal. What separates Eclipse Theia from other cloud IDE software is its extensibility; it can be modified using custom extensions, which allow you to craft a cloud IDE suited to your needs.
In this tutorial, you’ll deploy Eclipse Theia to your Ubuntu 18.04 server using Docker Compose, a container orchestration tool. You’ll expose it at your domain using nginx-proxy, an automated system for Docker that simplifies the process of configuring Nginx to serve as a reverse proxy for a container. You’ll also secure it using a free Let’s Encrypt TLS certificate, which you’ll provision using its specialized add-on. In the end, you’ll have Eclipse Theia running on your Ubuntu 18.04 server available via HTTPS and requiring the user to log in.
Prerequisites
- An Ubuntu 18.04 server with root privileges, and a secondary, non-root account. You can set this up by following our Initial Server Setup Guide for Ubuntu 18.04. For this tutorial the non-root user is
sammy
. - Docker installed on your server. Follow Step 1 and Step 2 of How To Install Docker on Ubuntu 18.04. For an introduction to Docker, see The Docker Ecosystem: An Introduction to Common Components.
- Docker Compose installed on your server. Follow Step 1 of How To Install Docker Compose on Ubuntu 18.04.
- A fully registered domain name. This tutorial will use
theia.your_domain
throughout. You can purchase a domain name on Namecheap, get one for free on Freenom, or use the domain registrar of your choice. - An A DNS record with
theia.your_domain
pointing to your server’s public IP address. You can follow this introduction to DigitalOcean DNS for details on how to add them.
Step 1 — Deploying nginx-proxy with Let’s Encrypt
In this section, you’ll deploy
nginx-proxy
and its Let’s Encrypt add-on using Docker Compose. This will enable automatic TLS certificate provisioning and renewal, so that when you deploy Eclipse Theia it will be accessible at your domain via HTTPS.For the purposes of this tutorial, you’ll store all files under
~/eclipse-theia
. Create the directory by running the following command:Navigate to it:
You’ll store the Docker Compose configuration for
nginx-proxy
in a file named nginx-proxy-compose.yaml
. Create it using your text editor:Add the following lines:
Here you’re defining two services that Docker Compose will run,
nginx-proxy
and its Let’s Encrypt companion. For the proxy, you specify jwilder/nginx-proxy
as the image, map HTTP and HTTPS ports, and define volumes that will be accessible to it during runtime.Volumes are directories on your server that the defined service will have full access to, which you’ll later use to set up user authentication. To achieve that, you’ll make use of the first volume from the list, which maps the local
/etc/nginx/htpasswd
directory to the same one in the container. In that folder, nginx-proxy
expects to find a file named exactly as the target domain, containing log-in credentials for user authentication in the htpasswd
format (username:hashed_password
).For the add-on, you name the Docker image and allow access to Docker’s socket by defining a volume. Then, you specify that the add-on should inherit access to the volumes defined for
nginx-proxy
. Both services have restart
set to always
, which orders Docker to restart the containers in case of crash or system reboot.Save and close the file.
Deploy the configuration by running:
Here you pass in the
nginx-proxy-compose.yaml
filename to the -f
parameter of the docker-compose
command, which specifies the file to run. Then, you pass the up
verb that instructs it to run the containers. The -d
flag enables detached mode, which means that Docker Compose will run the containers in the background.The final output will look like this:
You’ve deployed
nginx-proxy
and its Let’s Encrypt companion using Docker Compose. Now you’ll move on to set up Eclipse Theia at your domain and secure it.Step 2 — Deploying Dockerized Eclipse Theia
In this section, you’ll create a file containing any allowed log-in combinations that a user will need to input. Then, you’ll deploy Eclipse Theia to your server using Docker Compose and expose it at your secured domain using
nginx-proxy
.As explained in the previous step,
nginx-proxy
expects log-in combinations to be in a file named after the exposed domain, in the htpasswd
format and stored under the /etc/nginx/htpasswd
directory in the container. The local directory which maps to the virtual one does not need to be the same, as was specified in the nginx-proxy
config.To create log-in combinations, you’ll first need to install
htpasswd
by running the following command:The
apache2-utils
package contains the htpasswd
utility.Create the
/etc/nginx/htpasswd
directory:Create a file that will store the logins for your domain:
Remember to replace
theia.your_domain
with your Eclipse Theia domain.To add a username and password combination, run the following command:
Replace
username
with the username you want to add. You’ll be asked for a password twice. After providing it, htpasswd
will add the username and hashed password pair to the end of the file. You can repeat this command for as many logins as you wish to add.Now, you’ll create configuration for deploying Eclipse Theia. You’ll store it in a file named
eclipse-theia-compose.yaml
. Create it using your text editor:Add the following lines:
~/eclipse-theia/eclipse-theia-compose.yaml
In this config, you define a single service called
eclipse-theia
with restart
set to always
and theiaide/theia:next
as the container image. You also set init
to true
to instruct Docker to use init
as the main process manager when running Eclipse Theia inside the container.Then, you specify two environment variables in the
environment
section: VIRTUAL_HOST
and LETSENCRYPT_HOST
. The former is passed on to nginx-proxy
and tells it at what domain the container should be exposed, while the latter is used by its Let’s Encrypt add-on and specifies for which domain to request TLS certificates. Unless you specify a wildcard as the value for VIRTUAL_HOST
, they must be the same.Remember to replace
theia.your_domain
with your desired domain, then save and close the file.Now deploy Eclipse Theia by running:
The final output will look like:
Then, in your browser, navigate to the domain you’re using for Eclipse Theia. Your browser will show you a prompt asking you to log in. After providing the correct credentials, you’ll enter Eclipse Theia and immediately see its editor GUI. In your address bar you’ll see a padlock indicating that the connection is secure. If you don’t see this immediately, wait a few minutes for the TLS certificates to provision, then reload the page.
Now that you can securely access your cloud IDE, you’ll start using the editor in the next step.
Step 3 — Using the Eclipse Theia Interface
In this section, you’ll explore some of the features of the Eclipse Theia interface.

On the left-hand side of the IDE, there is a vertical row of four buttons opening the most commonly used features in a side panel.
Theia Ide Docker
This bar is customizable so you can move these views to a different order or remove them from the bar. By default, the first view opens the Explorer panel that provides tree-like navigation of the project’s structure. You can manage your folders and files here—creating, deleting, moving, and renaming them as necessary.
After creating a new file through the File menu, you’ll see an empty file open in a new tab. Once saved, you can view the file’s name in the Explorer side panel. To create folders right click on the Explorer sidebar and click on New Folder. You can expand a folder by clicking on its name as well as dragging and dropping files and folders to upper parts of the hierarchy to move them to a new location.
The next two options provide access to search and replace functionality. Following it, the next one provides a view of source control systems that you may be using, such as Git.
The final view is the debugger option, which provides all the common actions for debugging in the panel. You can save debugging configurations in the
launch.json
file.Theia Ide Github
The central part of the GUI is your editor, which you can separate by tabs for your code editing. You can change your editing view to a grid system or to side-by-side files. Like all modern IDEs, Eclipse Theia supports syntax highlighting for your code.
You can gain access to a terminal by typing
CTRL+SHIFT+`
, or by clicking on Terminal in the upper menu, and selecting New Terminal. The terminal will open in a lower panel and its working directory will be set to the project’s workspace, which contains the files and folders shown in the Explorer side panel.Theia Ide Java
