|
|
This is a modification of [simplegeo/nodejs-redis](https://github.com/simplegeo/nodejs-redis) , aiming to be compatible with LedisDB.
|
|
|
|
###Setup
|
|
Just copy (or move) the ledis directory into your project's **node_modules** directory.
|
|
|
|
cp -r /path/to/ledisdb/client/nodejs/ledis /path/to/your/node_modules/
|
|
|
|
###Example
|
|
Below is the total content of example.js, including the ledisDB's special commands.
|
|
|
|
|
|
var ledis = require("ledis"),
|
|
client = ledis.createClient();
|
|
|
|
client.on("error", function (err) {
|
|
console.log("Error " + err);
|
|
});
|
|
|
|
client.set("string key", "string val", ledis.print);
|
|
client.get("string key", ledis.print);
|
|
client.hset("hash key", "hashtest 1", "some value", ledis.print);
|
|
client.hset(["hash key", "hashtest 2", "some other value"], ledis.print);
|
|
client.hkeys("hash key", function (err, replies) {
|
|
console.log(replies.length + " replies:");
|
|
replies.forEach(function (reply, i) {
|
|
console.log(" " + i + ": " + reply);
|
|
});
|
|
});
|
|
|
|

client.lpush("list key", "1", "2", "3", ledis.print);
|

client.lrange("list key", "0", "2", ledis.print);
|
|
client.lclear("list key", ledis.print);
|
|
client.lrange("list key", "0", "2", ledis.print);
|
|
|
|
client.zadd("zset key", 100, "m", ledis.print);
|
|
client.zexpire("zset key", 40, ledis.print);
|
|
client.zttl("zset key", ledis.print);
|
|
|
|
client.bsetbit("bit key 1", 1, 1, ledis.print);
|
|
client.bsetbit("bit key 2", 1, 1, ledis.print);
|
|
client.bopt("and", "bit key 3", "bit key 1", "bit key 2", ledis.print);
|
|
client.bget("bit key 3", function(err, result){
|
|
if (result=="\x02"){
|
|
console.log("Reply: \\x02")
|
|
}
|
|
});
|
|
