# miniapps

## Description

* Update one or more MiniApps versions in a non-released native application version in a Cauldron  
* Perform multiple checks, including MiniApp dependencies analysis, to ensure compatibility with the target native application container  
* Generate and publish a new Container version  

## Syntax

`ern cauldron update miniapps <miniapps..>`

**Arguments**

`<miniapps..>`

* One or more package path to MiniApp(s) (delimited by spaces) to update in a target native application version in the Cauldron.
* The following types of MiniApp paths are not supported by this command :
  * File path (ex `file://Users/foo/MiniApp`)
  * Git path missing branch/tag or commit sha (ex: `https://github.com/foo/MiniApp.git`)
  * Registry path missing version (ex: `MiniApp`)
  * Registry path using a version range (ex: `MiniApp@^1.0.0`)
* Can also be set to **all** . In this case, all MiniApps will be updated to a single specific version specified by the `--targetVersion` option.

**Options**

`--containerVersion/-v <version>`

* Specify a version for the new container &#x20;
* **Default**  Incremental patch number of the current container version &#x20;

  Example: If the current container version is 1.2.3 and a version is not included in the command, the new container version will be 1.2.4. &#x20;

`--descriptor/-d <descriptor>`

* Update the MiniApps to a given target non-released native application version in the Cauldron matching the provided native application descriptor. &#x20;
* You can only pass a complete native application descriptor as the MiniApps updated using this command targets only a specific single native application version.\
  **Default** Lists all non-released native application versions from the Cauldron and prompts you to choose a descriptor.

  `--targetVersion`

  * Only used when running **ern cauldron update miniapps all**.
  * The target version to update all MiniApps to.

## Remarks

* If one MiniApp does not pass compatibility checks, the command will fail
