# .is\_active(id, version)

The is\_active function can be used to detect if a plugin is installed, and whether it matches a specific version. This function should be used in conjunction with bits soft-requirements system to block parts of your plugin to users who may not have all the required plugins.

The version paramater is optional and can be ommitted.

```javascript
plugins.is_active(id, version)
```

Example with Bit: Core 2025.2.0 installed

```javascript
const reqMet = plugins.is_active('bit-core', '2025.2.0');

console.log(reqMet)

// Output if everything matches
/*
{
    "installed": true,
    "activated": true,
    "match_version": true
}
*/

// Output if Bit: Core is not installed
/*
{
    "installed": false,
    "activated": null,
    "match_version": null
}
*/

// Output if Bit: Core is installed but not on the right version.
/*
{
    "installed": true,
    "activated": true,
    "match_version": false
}
*/

// Output if Bit: COre is installed but disabled
/*
{
    "installed": true,
    "activated": false,
    "match_version": null
}
*/
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://bit.lockyzdev.com/docs/dev/create-plugins/functions/plugins/.is_active-id-version.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
