Driver managements

CloudBeaver supports almost any database which has a JDBC driver.
It generally supports all drivers supported by DBeaver.

By default, do not enable all DBeaver drivers in CloudBeaver. They must be added to the server configuration on demand.

Adding new driver dependencies

Driver dependencies are configured in the folder server/drivers.
In order to add a new driver:

  • Create new folder for a new driver
  • Copy the POM file from any another driver config to the new directory
  • Change the module name and driver dependencies in the new POM file

Example of PostgreSQL driver config:

<project xmlns="" xmlns:xsi=""




Adding a new driver to the server

Enabled drivers are configured in the file, server/bundles/io.cloudbeaver.resources.drivers.base/plugin.xml.
You can copy an existing driver configuration to add a new one.

There are 3 configuration lines for each driver:

  1. <resource name="drivers/driver-name" /> – says that the file-system folder drivers/driver-name can be used to load driver jars.
  2. <bundle id="drivers.driver-name" /> – needed for driver configuration enable in the DBeaver platform
  3. <driver id="generic:driver-name" /> – enabled the DBeaver driver in CloudBeaver. The driver ID can be found in the DBeaver platform (in one of the database-specific plugin.xml files).

Package localization

Not all localization comes from the Cloudbeaver source code, some of it comes from the backend side. So, if you want to, for example, change or create localization for database objects, you need to do it in another repository, that is Here is a guide how you can contribute to dbeaver localization

To create or improve the localization for Cloudbeaver follow these steps:

Prepare for changes

  1. Fork repository
  2. Clone it to your local system.
  3. Make a new branch (for example, italian-localization).

    Make changes

  4. Find the package you want to change localization in.
    In Cloudbeaver all translatable resources are located in the locales folder. The path to the folder is [package-name]\src\locales\[locale-code].ts.
    For example, you can find basic UI language tokens in the core-localization\src\locales\[locale-code].ts file.
  5. Create localization file.

    For example, if you want to add localization for the Italian language create `it.tsfile next to theen.tsfile in the directory we have discussed before. After that, copy all content from theen.tsfile to theit.ts` file.
  6. Translate tokens to your language.
    Here is the structure of the language tokens: `[‘token-name’, ‘token-value’]`. You need to change only the second part, ‘token-value’.
    For example, if you wanted to translate the Loading… token, which is `[‘ui_processing_loading’, ‘Loading…’]`, it would look like this: `[‘ui_processing_loading’, ‘Caricamento in corso…’]`.
  7. Commit and Push your changes back to your repo.
  8. Click the Compare & pull request button.
  9. Click Create pull request to open a new pull request (in branch devel)

To find the right localization files, you can go to -> press Go to file -> paste en. in the input and you should see all available localization files.

Frontend technical overview

CloudBeaver frontend is a single page application written in React.
We use InversifyJS for dependency injection and MobX as a state management library. GraphQL is used to communicate with the server.

The application is written as a set of plugins organized in Lerna monorepo. The plugins can be developed independently and added to the final build by mentioning it in the configuration file.

The application uses Reshadow library and CSS modules for style incapsulation and supports light and dark themes.

We use Ag-Grid to display big and functionally rich tables and Codemirror to edit SQL queries.


  1. Run the local server as described in the Build and deploy section
  2. Execute

    cd webapp/
    lerna run dev --stream --scope=@cloudbeaver/product-default -- -- --env server=localhost:8978

    to run Webpack dev server

  3. Open localhost:3100 in web browser


The application consists of several plugins and submodules which are located in the webapp\packages folder.

  • core-administration – Administration API
  • core-app – Base application folder
  • core-authentication – Authentication API
  • core-blocks – Low-level common visual components
  • core-bootstrap – Common core package
  • core-cli – Command line tools for building & dev
  • core-connections – Connections API
  • core-di – Dependency injection related classes
  • core-dialogs – Main and context menues, modal windows
  • core-events – Logging
  • core-executor – Task scheduling API
  • core-extensions – Extensions API
  • core-localization – Localization API

  • plugin-ddl-viewer – Provides DDL for database objects
  • plugin-object-viewer – Provides Object Property View
  • plugin-sql-editor – Provides SQL-editor tab
  • product-default – Configure and build all plugins to the final application

Role management

You can use roles to manage connection permissions in CloudBeaver. As a role is added to a user, the role connections become available for the user on the main page.

The Admin and User roles are available by default.

Role Connections created in Easy Config Connections created in Administration Administration menu
Admin Yes Yes Yes
User Available by default. Can be deleted Not available by default. Can be added No

The Administrator can create custom roles on the Roles tab of the Administration menu.

Plugin system

Folder structure

  |-webapp                 # all frontend codes are here
    |-packages             # yarn workspaces managed by lerna
      |-core               # core package with common modules like GraphQL, 
        |                    dependency injection, and common app services
        |-cli              # core/plugin/product build configs (webpack, babel)
        |-administration   # administration API
        |-di               # dependency injection module
        |-blocks           # the module with basic components - buttons, tabs, tables, lists
        |-sdk              # GraphQL wrapping services
        |-dialogs          # menus, context menus, modal windows
        |-...              # other modules
        |-etc...            # other plugins
      |-product-default     # default application product package (with all plugins)

Plugin folder structure

common folder structure:

 |-node_modules    # dependencies
 |-lib             # after the build will contain the artifact
 |-public          # put static assets to this folder
 |-src             # keep source files here


Execute from cloudbeaver/webapp

Load all dependencies and init workspaces

```yarn run build```

Build all packages (plugins and the application) and the result will be placed in the `packages/{package-name}/lib` folder

```yarn run lint```

Lint all code

```yarn run lint-fix```

Lint all code and fix

## Build plugin
To build a single plugin execute
lerna run build --stream --scope=@cloudbeaver/plugin-name

## Build product
### Product folder structure is the same as for plugin
    |-node_modules     # dependencies
    |-lib              # after the build will contain the artifact
    |-public           # put static assets to this folder
    |-src              # keep source files here
The only difference in the build command is: `"build": "core-cli-build --mode=production --config ../core-cli/configs/webpack.product.config.js",` it uses product config, also contains `dev` command for starting development local build `"dev": "core-cli-build serve --mode=development --progress --config=../core-cli/configs/ --port=3100",`

The application package simple defines the list of plugins that should be included in the build
### Commands
Execute the command to build only the application without rebuilding the plugins

`lerna run build --stream --scope=@cloudbeaver/product-name`

## Development
1. To run a development build that watches file changes and rebuilds, you can use the `dev` command:
`lerna run dev --stream --scope=@cloudbeaver/product-default -- -- --env server=http://backend.server:8095`
It starts the dev server for `product-default`. It also proxies backend requests to `http://backend.server:8095`

2. Navigate `localhost:3100` to open the application

## Static assets
You can keep static assets like images, favicon, etc in the `public` folder in the plugin packages or app package.

Assets such as these will be copied to the application distributive. Assets with the same name will overwrite one another, but the Application public assets have higher priority over them all.

## Localization
See the example in the `core-administration` `AdministrationLocaleService.ts` and `locales` folder
