Obsidian to Hugo blog builder

Instructions to fork this repository

This repository contains my personal set up to build my Obsidian notes into a Hugo based blog. This will take 1 or 2 hours.

Fork this repo

Yes, fork this repo.

Prepare your Hugo blog

Either create a new hugo blog by following the instructions on their website: https://gohugo.io/getting-started/quick-start/ or import your hugo blog into hugoroot. Note that this script will overwrite some files that are needed to render links and images properly. Read more here why:

Copy and modify the build.sh script

The build.example.sh script has a few variables you can modify, but the most important piece is to inject your Obsidian vault into the vault directory, and also configure the root of where the blog is located. Copy into build.sh and change the script accordingly.

Import your vault in the build script

Again, you will need to copy your vault into the vault directory. I recommend using the Obsidian Git plugin to back up your notes to a private Git repository. I will use Github as a platform but anywhere else will do. Once your Vault is exported into git, you can use git to clone / submodule into the vault directory.

I personally use submodules. I run:

rm -rf ./vault
git submodule add [email protected]/ORG/REPO ./vault

Then I modify the build script with:

git submodule init
git submodule update

Add frontmatter in your Obsidian posts

Hugo requires frontmatter for the blog posts to be rendered and tagged appropriately. I use the Templater plugin to put dates and other things automatically. I created the following template:

---
title: <% tp.file.title %>
date: <% tp.file.creation_date("YYYY-MM-DD") %>
description:
tags:
---

This template is inserted on top of the posts that I want to render into a blog.

Push this to a repository

Push all your changes to a git repo. I use Netlify to deploy the blog. I:

1. Link my fork of this repo as a Netlify project
2. Add a Deploy Key to my Obsidian vault's repo so Netlify can download it
3. Trigger a deploy. Hopefully things will be super smooth!

Automatically deploying your blog on Obsidian updates

1. Create a Build hook in your Netlify application. You will get an URL like so: `https://api.netlify.com/build_hooks/12345"
2. Create a Github Action in your Obsidian repository. Create a file named .github/workflows/main.yml with the following contents:

name: Trigger Netlify Build
on: push
jobs:
  build:
    name: Request Netlify Webhook
    runs-on: ubuntu-latest
    steps:
      - name: Curl request
        run: curl -X POST -d {} https://api.netlify.com/build_hooks/12345

Boom! Whenever Obsidian Git pushes the changes, your blog will be updated right after.
