As you can see "del" command is in the list.
如您所见，“del”命令在列表中。
And this command allow you delete keys from selected db as Jonatan answered.

As everyone above has stated you can use del function. You can assure the successful delete operation using this syntax.
如上所述，您可以使用 del 函数。您可以使用此语法确保删除操作成功。
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) 1in successful operation.
因为 DEL 命令会(integer) 1在操作成功时返回。
redis 127.0.0.1:6379> DEL key
Success: (integer) 1
Unsuccess: (integer) 0

If I remember things correctly, delshould do it.
如果我没记错的话，del应该这样做。

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);
});

Using sailsJs you can do this :
使用sailsJs你可以做到这一点：
let id_todel = "5b845f9ea7f954bb732fdc52";
await sails.getDatastore('redis').leaseConnection(function during(db, proceed) {
db.del(id_todel );
return proceed(undefined, undefined);
});
