Initialization

For simple initialization, you need to have an appId for creating an app in Ramper, please visit this link to create a new app. Then you can use the following code:

import {
  init
} from "@ramper-v2/multi";
 
 
...
 
const handleInit = async () => {
  await init({
    appId: "your-app-id",
  });
};
 

Notes

You can also use some custom parameters to initialize Ramper. Please note that those optional parameters are only applied if config from your app is not provided.

Here are some parameters you can use:

Parameter	Type	Description
config	Record<string, string>	This one will be provided by the Ramper team
theme	dark or light	This will change theme for wallet UI
coinInfo	CoinInfo	The list of coins to display and calulation
language	en or kr	Select supported language
walletTabs	string	Select initial wallet tab
partner	string	Select partner default is ramper
logoURI	string	Logo URI for display through the wallet

User sign-up & sign-in

import { signInWithProvider, signIn } from '@ramper-v2/multi'
 
const signInResult = await signInWithProvider({ provider });
 
const signInResult = await signIn();

There are two ways to sign in a user. The first way is to use the signInWithProvider function, which takes a provider as an argument. The provider can be one of the following: google, facebook, or email. The second way is to use the signIn function, which will show a modal with all the available providers.

Get the current signed in user

import { getUser } from '@ramper-v2/multi'
 
const user = await getUser()
 
if (user) {
  console.log(user)
}

Logging Out

Users can log out or disconnect their wallet with:

import { signOut } from '@ramper-v2/multi'
 
await signOut()

Yup, it really is just that easy!

If there's any feature you would like to see or design patterns you would like for the Ramper team to adopt.
