Miro OAuth2.0

Prerequisites:

Create an app in Miro (https://miro.com/app/settings/user-profile/apps)
Install Localtunnel (or similar, such as Ngrok)

How to start:

Clone or download repo
cd to root folder
Run npm install to install dependencies.
Create a .env file in the root folder, and set the following variables:

clientID={YOUR_CLIENT_ID)
clientSecret={YOUR_CLIENT_SECRET}
redirectURL={YOUR_REDIRECT_URL}
boardId={MIRO_BOARD_ID}

In this example, we will host our local environment over HTTPS using Localtunnel. (You can use other services such as ngrok as well.)

Install localtunnel (or your preferred service)
Generate your HTTPS URL (if using localtunnel, lt --port 3000) for localhost
Copy this HTTPS URL and paste it in the Redirect URI for OAuth2.0 box in your Miro app settings
Paste this same HTTPS URL into your .env redirectURL variable (above)
From your desired Miro board, grab the board ID from the URL and paste it into your .env boardId variable (above)
From your Miro app settings, grab the Client ID and Client Secret. Paste this into your .env clientId and clientSecret variables (above)

How to run the project

Run npm run start to run the project
Your express server console should reflect "Listening on Localhost 3000" (or the port of your choice)
Once your server is running, copy the Installation URL for your app, under "Share App" in the Miro App UI
Navigate to the authorization screen via the Installation URL and authorize/install the app
This should redirect you to your Localtunnel URL, where you will see the JSON API response from the GET Board API displayed in the browser

About the app

This sample app is intended to demonstrate the OAuth 2.0 flow that is required to call Miro's V2 APIs. Devs may consider using this Node.js demo as a structural basis for any other preferred language/framework. NOTE: Any comments with "--->" signify part of a significant step in the flow. Comments without "--->" are added for additional reference on code.

For the full guide on Miro's OAuth 2.0 flow, please see the documentation here: https://beta.developers.miro.com/docs/getting-started-with-oauth
