Read JSON File From Database in Anuglar

Question

Is there anyway to read a JSON file from data base. Make some changes and save it back to database in Angular. I had googled it always shows the reading of JSON file from Asset Folder which is not my requirement.

I was expecting to read a file from database store it in a variable and make some changes and store it back to database.

Answer 1

JSON, JavaScript Object Notation, is the standard representation of object within web apps. What this means is that retrieving your JSON from the database can be saved to a variable in your Angular app. Then you can make your changes and send an update command.

This is demonstrated in a StackBlitz example with explicit functions to do database reads and writes which you will have to update.

Additionally, if the database stores the JSON as a serialized string, you will have to encode/decode using JSON.parse and JSON.stringify on the variable representing the server data.
