About

why to use replpersist?

• no subdependencies
• it's sync, meaning you don't have to deal with async stuff in your code
• it's super leightweight. It only takes up 3.45kb unpacked and 1.6kb packed. In fact, it got 29% leighter in the latest update. In comprison, this documentation alone is 3.37kb+
• it's super fast since you don't need to request the data again when you want to access it, the data is cached and can be accessed in a fraction of a millisecond like a normal object.
• It's high level, you don't need to worry about handling request stuff etc

Documentation

Import module

Import the module like this: const Database = require("replpersist");

Database constructor

A database instance can be created like this: let myDB = new Database(dbName[,upload delay (in minutes)][,start value]);

additionally you can use Database.databases to list all databases.

Database instance

myDB.data

this is where your data is stored. You can interact with it like a normal array, and it also can be changed to an object. There's functions that help interacting with it. More information below.

myDB.name

the name of the database

myDB.onupload

if set it's called when the database is uploaded automatically or manually. The data is passed as a parameter

myDB.reset()

resets the whole database.

myDB.upload()

to manaully upload the database, independent of the automatic uploading cycle. Call after storing important data. The database will upload automatically once all 2 minutes or any other value that has been set when creating the database.

additional array functions

intended to use on myDB.data, but can be used on any array.

array.add(name,value)

adds/pushes the following object: { "name":name, "content":value }

array.addCustom(nameProp,contentObj)

will add/push contentObj if there's no other object with the name value of nameProp. If duplicates don't matter, use javascript's normal array.push.

array.clear()

empties array

array.del(delname)

deletes object with the property name being delname. For instance, if you have the array [{name:"test"}] you can delete the object by using array.del("test")

array.delCustom(nameProp,nameValue)

deletes object with the property nameProp having the value of nameValue. For instance, if you have the array [{someProp:"hello world"}] you can delete it by using delCustom("someProp","hello world")

array.delItem(item)

if you know what the value of the item you want to delete is, you can use this function. If you have the array ["delete","the","second","item"] you can call array.delItem("the") to remove the second item.

array.f(nameValue)

same as array.del, but it returns the found item instead of deleting it

array.fAll(nameProp,nameVal)

same as array.fCustom, but it returns a list of all found elements instead of just the first one

array.fCustom(nameProp,nameVal)

same as array.delCustom, but it returns the item instead of deleting it

array.fi(nameVaö)

same as array.f, but only returns the index

array.fiCustom(nameProp,nameVal)

same as array.fCustom, but only returns index
