I'm developing an app with firebase ( RealTime ) and ionic3 .
I do not have much knowledge in this technology, and I was not able to clarify a doubt with my researches:
Is it possible to create a query-only table? For example , I need a table to ONLY bring products to search, is this possible?
I do not know if I understood your question well, but, as described in the documentation: link
Database rules require Firebase Authentication and grant read and write permissions to users only authenticated. The default rules ensure that the database is not accessed by anyone before being configured. Then customize them according to your needs. Check out some common examples:
// These rules don't allow anyone read or write access to your database
{
"rules": {
".read": false,
".write": false
}
}
Therefore, by setting these rules, you can configure each user's level of access to the data, documentation link , there is a more in-depth explanation of how to define these rules for users.
