my node needs the nodes context storage to be persistent, for that, I can set
`contextStorage` to `localfilesystem` in settings.js.
can I change that setting from my node? how?
in the [docs](https://nodered.org/docs/user-guide/context#saving-context-data-to-the-file-system) it is mentioned that you can use multiple context storages:
```auto
contextStorage: {
default: "memoryOnly",
memoryOnly: { module: 'memory' },
file: { module: 'localfilesystem' }
}
```
how do I use a contextStorage different to `default` for my nodes context?
If it is not possible to change these setting from code, is there a recommended way to tell users about the required settings?

you have to edit the settings.js file and restart node-red.
For an explaination of how it works, read [A guide to understanding 'Persistent Context'](https://discourse.nodered.org/t/a-guide-to-understanding-persistent-context/4115)
