Denobase

Denobase is a database written in TypeScript for Deno.

Usage

For this tutorial, we will use ‘db’ as the Database.

import { Database, Get } from "https://deno.land/x/denobase@1.0.1/mod.ts"
let db = new Database("dataStore")

‘Get’ is the return type for ‘.get()’ method.

Set (key: string, value: string | number): boolean

let set: boolean = db.set("test", "Hello Deno!") // true

Get (key: string): string | number | undefined

let get: Get = db.get("test") // "Hello Deno!"

Has (key: string): boolean

let has: boolean = db.has("test") // true
let falsehas: boolean = db.has("testt") // false

Delete (key: string): boolean

let testSet: boolean = db.set("testDelete", "Hello World!") //true
let testDelete: boolean = db.delete("testDelete") // true
let testHas: boolean = db.has("testDelete") // false

All (): object

let all: object = db.all() // { test: "Hello Deno!" }

Clear (): boolean

let clear: boolean = db.clear() // true
let testAll = db.all() // {}

Write (): boolean

This method will write all the data to a .json file. The file name will be the same as the database name.

db.set("set", "Hello!")
db.write()

dataStore.json

{ "set": "Hello!" }

Read (): Promise<boolean>

Denobase use Map for the database.
If you don’t use ‘read’, denobase will create an empty Map.
Use ‘read’ to read json data from the json file that is created using ‘write’.

Example

main.ts

import { Database } from "https://deno.land/x/denobase@1.0.0/mod.ts"
let db = new Database("denobase")
db.set("color", "Red")
db.write()

It will create a new json file
denobase.json

{ "color": "Red" }

If you try to log all value in the database, it will return an empty object because it create a new Map.

import { Database } from "https://deno.land/x/denobase@1.0.0/mod.ts"
let db = new Database("denobase")
db.all() // {}

If you use ‘read’

import { Database } from "https://deno.land/x/denobase@1.0.0/mod.ts"
let db = new Database("denobase")
await db.read()
db.all() // { color: "Red" }

Note:

Always use ‘await’ and put it after creating new database.
Always make sure the database name is the same
