|
|
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/github.com/src/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) {

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"){
