# Active content
_Active content_ is a generic name for powerful features in Trilium, these range from customizing the UI to advanced scripting that can alter your notes or even your PC.
## Safe import
Active content problem of safety, especially when this active content comes from a third-party such as if it is downloaded from a website and then imported into Trilium.
When [importing](Import%20%26%20Export.md) .zip archives into Trilium, _safe mode_ is active by default which will try to prevent untrusted code from executing. For example, a [custom widget](../Scripting/Frontend%20Basics/Custom%20Widgets.md) needs the `#widget` [label](../Advanced%20Usage/Attributes/Labels.md) in order to function; safe import works by renaming that label to `#disabled:widget`.
## Safe mode
Sometimes active content can cause issues with the UI or the server, preventing it from functioning properly. <a class="reference-link" href="../Advanced%20Usage/Safe%20mode.md">Safe mode</a> allows starting Trilium in such a way that active content is not loaded by default at start-up, allowing the user to fix the problematic scripts or widgets.
## Types of active content
These are the types of active content in Trilium, along with a few examples of what untrusted content of that type could cause:
| Name | Disabled on a safe [import](Import%20%26%20Export.md) | Description | Potential risks of untrusted code |
| --- | --- | --- | --- |
| [Front-end scripts](../Scripting/Frontend%20Basics.md) | Yes | Allow running arbitrary code on the client (UI) of Trilium, which can alter the user interface. | A malicious script can execute server-side code, access un-encrypted notes or change their contents. |
| <a class="reference-link" href="../Scripting/Frontend%20Basics/Custom%20Widgets.md">Custom Widgets</a> | Yes | Can add new UI features to Trilium, for example by adding a new section in the <a class="reference-link" href="UI%20Elements/Right%20Sidebar.md">Right Sidebar</a>. | The UI can be altered in such a way that it can be used to extract sensitive information or it can simply cause the application to crash. |
| <a class="reference-link" href="../Scripting/Backend%20scripts.md">Backend scripts</a> | Yes | Can run custom code on the server of Trilium (Node.js environment), with full access to the notes and the database. | Has access to all the unencrypted notes, but with full access to the database it can completely destroy the data. It also has access to execute other applications or alter the files and folders on the server). |
| <a class="reference-link" href="../Note%20Types/Web%20View.md">Web View</a> | Yes | Displays a website inside a note. | Can point to a phishing website which can collect the data (for example on a log in page). |
| <a class="reference-link" href="../Note%20Types/Render%20Note.md">Render Note</a> | Yes | Renders custom content inside a note, such as a dashboard or a new editor that is not officially supported by Trilium. | Can affect the UI similar to front-end scripts or custom widgets since the scripts are not completely encapsulated, or they can act similar to a web view where they can collect data entered by the user. |
| <a class="reference-link" href="../Theme%20development/Custom%20app-wide%20CSS.md">Custom app-wide CSS</a> | No | Can alter the layout and style of the UI using CSS, applied regardless of theme. | Generally less problematic than the rest of active content, but a badly written CSS can affect the layout of the application, requiring the use of <a class="reference-link" href="../Advanced%20Usage/Safe%20mode.md">Safe mode</a> to be able to use the application. |
| [Custom themes](../Theme%20development) | No | Can change the style of the entire UI. | Similar to custom app-wide CSS. |
| <a class="reference-link" href="Themes/Icon%20Packs.md">Icon Packs</a> | No | Introduces new icons that can be used for notes. | Generally are more contained and less prone to cause issues, but they can cause performance issues (for example if the icon pack has millions of icons in it). |
## Active content badge
Starting with v0.102.0, on the <a class="reference-link" href="UI%20Elements/New%20Layout.md">New Layout</a> a badge will be displayed near the note title, indicating that an active content is detected. Clicking the badge will reveal a menu with various options related to that content type, for example to open the documentation or to configure the execution of scripts.
For some active content types, such as backend scripts with custom triggering conditions a toggle button will appear. This makes it possible to easily disable scripts or widgets, but also to re-enable them if an import was made with safe mode active.

# Backend scripts
Unlike [front-end scripts](Frontend%20Basics.md) which run on the client / browser-side, back-end scripts run directly on the Node.js environment of the Trilium server.
Back-end scripts can be used both on a <a class="reference-link" href="../Installation%20%26%20Setup/Server%20Installation.md">Server Installation</a> (where it will run on the device the server is running on), or on the <a class="reference-link" href="../Installation%20%26%20Setup/Desktop%20Installation.md">Desktop Installation</a> (where it will run on the PC).
## Advantages of backend scripts
The benefit of backend scripts is that they can be pretty powerful, for example to have access to the underlying system, for example it can read files or execute processes.
However, the main benefit of backend scripts is that they have easier access to the notes since the information about them is already loaded in memory. Whereas on the client, notes have to be manually loaded first.
## Creating a backend script
Create a new <a class="reference-link" href="../Note%20Types/Code.md">Code</a> note and select the language _JS backend_.
## Running backend scripts
Backend scripts can be either run manually (via the Execute button on the script page), or they can be triggered on certain events.
In addition, scripts can be run automatically when the server starts up, on a fixed time interval or when a certain event occurs (such as an attribute being modified). For more information, see the dedicated <a class="reference-link" href="Backend%20scripts/Events.md">Events</a> page.
## Script API
Trilium exposes a set of APIs that can be directly consumed by scripts, under the `api` object. For a reference of this API, see <a class="reference-link" href="Script%20API/Backend%20API.dat">Backend API</a>.

# Frontend Basics
## Frontend API
Front-end scripts are custom JavaScript notes that are run on the client (browser environment)
The frontend api supports two styles, regular scripts that are run with the current app and note context, and widgets that export an object to Trilium to be used in the UI. In both cases, the frontend api of Trilium is available to scripts running in the frontend context as global variable `api`. The members and methods of the api can be seen on the [Script API](Script%20API.md) page.
There are four flavors of front-end scripts:
| | |
| --- | --- |
| Regular scripts | These are run with the current app and note context. These can be run either manually or automatically on start-up. |
| <a class="reference-link" href="Frontend%20Basics/Custom%20Widgets.md">Custom Widgets</a> | These can introduce new UI elements in various positions, such as near the <a class="reference-link" href="../Basic%20Concepts%20and%20Features/UI%20Elements/Note%20Tree.md">Note Tree</a>, content area or even the <a class="reference-link" href="../Basic%20Concepts%20and%20Features/UI%20Elements/Right%20Sidebar.md">Right Sidebar</a>. |

These can simply introduce new buttons or graphical elements to the bar. |
| <a class="reference-link" href="../Note%20Types/Render%20Note.md">Render Note</a> | This allows rendering custom content inside a note, using either HTML or Preact JSX. |
For more advanced behaviors that do not require a user interface (e.g. batch modifying notes), see <a class="reference-link" href="Backend%20scripts.md">Backend scripts</a>.
## Scripts
Scripts don't have any special requirements. They can be run at will using the execute button in the UI or they can be configured to run at certain times using [Attributes](../Advanced%20Usage/Attributes.md) on the note containing the script.
Scripts don't have any special requirements. They can be run manually using the _Execute_ button on the code note or they can be run automatically; to do so, set the `run` [label](../Advanced%20Usage/Attributes/Labels.md) to either:
### Global Events
* `frontendStartup` - when Trilium frontend starts up (or is refreshed), but not on mobile.
* `mobileStartup` - when Trilium frontend starts up (or is refreshed), on mobile.
This attribute is called `#run` and it can have any of the following values:
* `frontendStartup` - executes on frontend upon startup.
* `mobileStartup` - executes on mobile frontend upon startup.
* `backendStartup` - executes on backend upon startup.
* `hourly` - executes once an hour on backend.
* `daily` - executes once a day on backend.
### Entity Events
These events are triggered by certain [relations](../Advanced%20Usage/Attributes.md) to other notes. Meaning that the script is triggered only if the note has this script attached to it through relations (or it can inherit it).
* `runOnNoteCreation` - executes when note is created on backend.
* `runOnNoteTitleChange` - executes when note title is changed (includes note creation as well).
* `runOnNoteContentChange` - executes when note content is changed (includes note creation as well).
* `runOnNoteChange` - executes when note is changed (includes note creation as well).
* `runOnNoteDeletion` - executes when note is being deleted.
* `runOnBranchCreation` - executes when a branch is created. Branch is a link between parent note and child note and is created e.g. when cloning or moving note.
* `runOnBranchDeletion` - executes when a branch is delete. Branch is a link between parent note and child note and is deleted e.g. when moving note (old branch/link is deleted).
* `runOnChildNoteCreation` - executes when new note is created under this note.
* `runOnAttributeCreation` - executes when new attribute is created under this note.
* `runOnAttributeChange` - executes when attribute is changed under this note.
> [!NOTE]
> Backend scripts have more powerful triggering conditions, for example they can run automatically on a hourly or daily basis, but also on events such as when a note is created or an attribute is modified. See the server-side <a class="reference-link" href="Backend%20scripts/Events.md">Events</a> for more information.
## Widgets
Conversely to scripts, widgets do have some specific requirements in order to work. A widget must:
Widgets require a certain format in order for Trilium to be able to integrate them into the UI.
* Extend [BasicWidget](https://triliumnext.github.io/Notes/frontend_api/BasicWidget.html) or one of it's subclasses.
* Create a new instance and assign it to `module.exports`.
* Define a `parentWidget` member to determine where it should be displayed.
* Define a `position` (integer) that determines the location via sort order.
* Have a `#widget` attribute on the containing note.
* Create, render, and return your element in the render function.
* For [BasicWidget](https://triliumnext.github.io/Notes/frontend_api/BasicWidget.html) and [NoteContextAwareWidget](https://triliumnext.github.io/Notes/frontend_api/NoteContextAwareWidget.html)you should create `this.$widget` and render it in `doRender()`.
* For [RightPanelWidget](https://triliumnext.github.io/Notes/frontend_api/RightPanelWidget.html) the `this.$widget` and `doRender()` are already handled and you should instead return the value in `doRenderBody()`.
* For legacy widgets, the script note must export a `BasicWidget` or a derived one (see <a class="reference-link" href="Frontend%20Basics/Custom%20Widgets/Note%20context%20aware%20widget.md">Note context aware widget</a> or <a class="reference-link" href="Frontend%20Basics/Custom%20Widgets/Right%20pane%20widget.md">Right pane widget</a>).
* For Preact widgets, a built-in helper called `defineWidget` needs to be used.
### parentWidget

* `left-pane` - This renders the widget on the left side of the screen where the note tree lives.
* `center-pane` - This renders the widget in the center of the layout in the same location that notes and splits appear.
* `note-detail-pane` - This renders the widget _with_ the note in the center pane. This means it can appear multiple times with splits.
* `right-pane` - This renders the widget to the right of any opened notes.
## Script API
The front-end API of Trilium is available to all scripts running in the front-end context as global variable `api`. For a reference of the API, see <a class="reference-link" href="Script%20API/Frontend%20API">Frontend API</a>.

To position the widget somewhere else, just change the value passed to `get parentWidget()` for legacy widgets or the `parent` field for Preact. Do note that some positions such as `note-detail-pane` and `right-pane` have special requirements that need to be accounted for (see the table above).

## Custom position
## Custom position
The position of a custom widget is defined via a `position` integer.
In legacy widgets:
```
class MyWidget extends api.BasicWidget {
// [..
get position() { return 10; }
}
```
In Preact widgets:
```
export default defineWidget({
// [...]
position: 10
});
```
