Database on JavaScript
Storing and structuring your application data on JavaScript.
Providing a standard Store Interface and Redis-like API that you can use in wherever.
Chinese version
Installation
Loading via script tag:
<script style="text/javascript" src="/path/to/script/min.js">
With node previously installed:
$ npm install min
If you using SeaJS, you can install with spm:
$ spm install iwillwen/min
If you are using component, you can install it with:
$ component install iwillwen/mindb
Or bower?:
$ bower install mindb
Basic Usage
Common key-value via such as SET
, GET
, etc.
min.set('foo', 'bar', function(err) {
if (err) {
return console.error(err);
}
min.get('foo', function(err, value) {
if (err) {
return console.error(err);
}
console.log(value); //=> bar
});
});
Basic commands
set
Set the value of a key (key, value[, callback])
setnx
Set the value of a key, only if the key does not exist (key, value[, callback])
setex
Set the value and expiration of a key (key, seconds, value[, callback])
psetex
Set the value and expiration in milliseconds of a key (key, millseconds, value[, callback])
mset
Set multiple keys to multiple values (plainObject[, callback])
msetnx
Set multiple keys to multiple values, only if none of the keys exist (plainObject[, callback])
append
Append a value to a key (key, value[, callback])
get
Get the value of a key (key[, callback])
mget
Get the values of a set of keys (keys[, callback])
getset
Set the value of a key and return its old value (key, value[, callback])
strlen
Get the length of a key (key[, callback])
incr
Increment the integer value of a key by one (key[, callback])
incrby
Increment the integer value of a key by the given amount (key, increment[, callback])
incrbyfloat
Increment the float value of a key by the given amount (key, increment[, callback])
Hash, List, Set, Sorted Set
Maybe you can get the way by browsing Redis Commands. XD
Sweet
Nested Callbacks? Maybe you would prefer Promise:
min.incr('user_id')
.then(function(curr) {
return min.hmset('user-' + curr, {
name: 'Will Wen Gunn',
id: 'iwillwen',
email: 'willwengunn@gmail.com'
});
})
.then(function(key) {
var id = key.substr(5);
return min.sadd('user-msg-' + id, 'WelCome!');
})
.then(function(length) {
// ...
})
.catch(function(err) {
console.log(err);
});
Anymore else? How about MULTI
?
min.multi()
.incr('msg-seq')
.incr('msg-seq')
.incr('msg-seq')
.exec(function(err, results) {
if (err) {
return console.error(err);
}
console.log(results); //=> [ [ 1 ], [ 2 ], [ 3 ] ]
});
SWEET! Let's run to Harmony(ES2015)!
async _ => {
var userId = await min.incr('users:id:seq')
await min.hmset(`user:${userId}`, {
name: 'Will Wen Gunn',
sign: 'iwillwen',
homepage: 'http://lifemap.in'
})
await min.sadd(`user:${userId}:msgs`, 'Welcome')
}
Support multiple databases:
var Min = min.fork();
Min.set('foo', 'bar')
.then(/*...*/)
.catch(/*...*/);
