A self-hosted calendar and scheduler server.

Nettu scheduler

Overview

Nettu scheduler is a self-hosted calendar and scheduler server that aims to provide the building blocks for building calendar / booking apps with ease. It has a simple REST API and also a JavaScript SDK and Rust SDK.

It supports authentication through api keys for server - server communication and JSON Web Tokens for browser - server communication.

Features

• Booking: Create a Service and register Users on it to make them bookable.
• Calendar Events: Supports recurrence rules, flexible querying and reminders.
• Calendars: For grouping Calendar Events.
• Freebusy: Find out when Users are free and when they are busy.
• Metadata queries: Add key-value metadata to your resources and then query on that metadata
• Webhooks: Notifying your server about Calendar Event reminders.

Quick start

First of all we will need a running instance of the server. The quickest way to start one is with docker:

docker run -p 5000:5000 fmeringdal/nettu-scheduler:latest

or if you want to build it yourself with cargo:

cd scheduler
cargo run inmemory

Both of these methods will start the server with an inmemory data store which should never be used in production, but is good enough while just playing around. For information about setting up this server for deployment, read here.

Now when we have the server running we will need an Account. To create an Account we will need the CREATE_ACCOUNT_SECRET_CODE which you will find in the server logs during startup (it can also be set as an environment variable).

curl -X POST -H "Content-Type: application/json" -d '{"code": "REPLACE_ME"}' -v http://localhost:5000/api/v1/account

The previous command will create an Account and the associated secretApiKey which is all you need when your application is going to communicate with the Nettu Scheduler server.

Quick example of how to create and query a user

export SECRET_API_KEY="REPLACE_ME"

# Create a user with metadata
curl -X POST -H "Content-Type: application/json" -H "x-api-key: $SECRET_API_KEY" -d '{"metadata": { "groupId": "123" }}' http://localhost:5000/api/v1/user

# Get users by metadata
curl -H "x-api-key: $SECRET_API_KEY" "http://localhost:5000/api/v1/user/meta?key=groupId&value=123"
