API

Instance

1. storage(dir, opts) a. opts.throws # if throws errors b. opts.max # the max number of item in this storage c. opts.ttl # the default ttl of each items d. interval # the interval time to check ttl items

Original API as localStorage in browser (Sync)

1. storage.length
2. storage.key(index)
3. storage.getItem(key)
4. storage.setItem(key, value, opts) # set opts.ttl as the time to live
5. storage.removeItem(key)
6. storage.clear(all) # if [all] is true, remove the dir itself including all sub-dirs

Extra API (Async)

1. storage.get(key).then((value) => {})
2. storage.set(key, value, opts).then(() => {})
3. storage.remove(key).then(() => {})
4. storage.list().then(([{key: value}, ...]) => {})
5. storage.valueOf().then(({key: value, ...}) => {})
6. storage.cleanup(all).then(() => {}) # if[all] is true, remove the dir itself including all sub-dirs
7. storage.cleanout().then(() => {}) # remove all of the outdated items
