Node_redis - how to remove a key?
72,330
Solution 1
Here you can see what redis commands are work in this library node_redis github
As you can see "del" command is in the list.
And this command allow you delete keys from selected db as Jonatan answered.
Solution 2
You can del
use like this:
redis.del('SampleKey');
Solution 3
As everyone above has stated you can use del function. You can assure the successful delete operation using this syntax.
client.del('dummyvalue', function(err, response) {
if (response == 1) {
console.log("Deleted Successfully!")
} else{
console.log("Cannot delete")
}
})
Because the DEL command will return (integer) 1
in successful operation.
redis 127.0.0.1:6379> DEL key
Success: (integer) 1
Unsuccess: (integer) 0
Solution 4
If I remember things correctly, del
should do it.
Solution 5
Hope this will help you
let redis = require("redis");
var redisclient = redis.createClient({
host: "localhost",
port: 6379
});
redisclient.on("connect", function () {
console.log("Redis Connected");
});
redisclient.on('ready', function () {
console.log("Redis Ready");
});
redisclient.set("framework", "AngularJS", function (err, reply) {
console.log("Redis Set" , reply);
});
redisclient.get("framework", function (err, reply) {
console.log("Redis Get", reply);
});
redisclient.del("framework",function (err, reply) {
console.log("Redis Del", reply);
});

Is there any way to remove/delete an entry by key, using Node_redis? I can't see any such option from the docs..

TigOldBitties over 7 years@Elephant hdel is not there but it works. The reference should be redis.io/commands since "It supports all Redis commands" (quoted from github github.com/NodeRedis/node_redis).
