Firebase for TypeScript
Introduction
When working with Firebase and TypeScript creating Classes for Firestore Documents can be a bit annoying. As there is not standard way of parsing and writing your Class to a Firestore Document, every project uses an different way.
The Firebase for TypeScript will change that by providing a standard way of using Classes that can then be stored into the Firestore Database. It makes creating, reading and maintaining Firestore Document Classes easy and consistent across projects.
Installation
Installation for Admin SDK (Functions, backend etc.)
npm install firebase-admin @janwuesten/firebase-admin-typescript
Installation for Web SDK (requires Web version 9)
npm install firebase @janwuesten/firebase-typescript
Installation for react native
Visit the documentation on GitHub Wiki to view installation steps for react native.
Basic usage example
Admin SDK
import { getFirestore } from "firebase-admin/firestore"
import { DocumentClass, DocumentClassDefineProps } from "@janwuesten/firebase-admin-typescript"
export class Account extends DocumentClass {
username: string = ""
firstName: string | null = null
lastname: string | null = null
definition({ define, defineCollection }: DocumentClassDefineProps): void {
// Define a prop
define("username", "string")
define("firstName", "string")
define("lastName", "string")
// Define what collection will be used
defineCollection(() => getFirestore().collection("account"))
}
}Web SDK
// firestore is the output of getFirestore()
import { firestore } from "@/firestore"
import { collection } from "firebase/firestore"
import { DocumentClass, DocumentClassDefineProps } from "@janwuesten/firebase-typescript"
export class Account extends DocumentClass {
username: string = ""
firstName: string | null = null
lastname: string | null = null
definition({ define, defineCollection }: DocumentClassDefineProps): void {
// Define a prop
define("username", "string")
define("firstName", "string")
define("lastName", "string")
// Define what collection will be used
defineCollection(() => collection(firestore, "account"))
}
}Setting or creating a document
const account = new Account()
account.username = "MyUsername"
await account.set()
// Created document ID:
console.log(account.id)Getting a document
const account = new Account("document id")
if (await account.get()) {
console.log("Account does exist")
} else {
console.log("Account does not exist")
}Updating a document
const account = new Account("document id")
await account.get()
account.username = "MyNewUsername"
await account.update()
// You can also use:
// await account.set()Deleting a document
const account = new Account("document id")
await account.delete()For more information on how to use firebase-typescript with all its features visit the documentation on GitHub Wiki here.
