Host Your Site Under Your Domain on IPFS

This is a step-by-step tutorial for hosting your website under your domain on IPFS, from zero, on a DigitalOcean Ubuntu 16.04.3 x64 Droplet (i am using the $10 variant with 2GB RAM).

Install IPFS

Log in as root.

First, make sure the system is up to date, and install tar and wget:

Overview

Scenario

Your VPS provider doesn't support ISO mount
Your VPS has low RAM and cannot load whole ISO image
Your current /boot is to small to contain ISO file

Workaround

Boot low memory ISO (CorePure64.iso ~ 14MB)
Create new partition ~1GB / size of your ISO
dd your ISO into that partition

Deploy Next.js static to GitLab pages

Create a basic GitLab CI config:

$ cat .gitlab-ci.yml
image: node

before_script:
 - npm install

Send email from Cloudflare Workers via MailChannels

Cloudflare announced a partnership with MailChannels that allows you to send free email via workers.

The example code that MailChannels supplied wasn't working so I fixed it here to make testing easy.

Add include:relay.mailchannels.net to your domain's SPF record.
Update the code below with your email addresses
Create worker, paste code, save and deploy and test

	// problem:
	// when subscribing to`HasuraConnect.subscription`, a websocket connection is created on the first subscription
	// call. The websocket connection is created only once with the initial subscription and the provided TokenInterceptor
	// or headers. When the token expires during an active subscription, HasuraConnect doesn't stop the subscription, or try
	// to reconnect with the latest token in in the TokenInterceptor nor does it throw an error. It'll keep calling `onRequest`
