In Node.js applications, Redis is often used as a caching layer or session store due to its high-performance data storage and retrieval. A common scenario is storing JSON objects representing user information or application state, and retrieving these values when necessary.
You can store JSON by stringifying it before setting into Redis. Later, when you retrieve that value, you have to parse it back into an object.
In this example, we use
JSON.stringify() to convert the JSON object into a string before storing and
JSON.parse() to convert the string back to a JSON object after retrieving.
erris not checked which could potentially lead to unhandled exceptions.
In Redis, there is no native support for JSON. So, forgetting to stringify before setting or parse after getting the JSON values is a common mistake. Always remember to convert your JSON to a string before setting it, and parse it back into an object when retrieving.
Q: Can I store nested JSON objects in Redis?
A: Yes, you can. Since you are converting the JSON object to a string before storing, the complexity of the object doesn't matter as long it can be validly stringified by
