og image generator
Generate open graph images for you awesome blogs.
Disclaimer: This is created for my personal use but can be used in other projects with similar requirements.
The Problem
I wanted a solution that will automatically create open graph images for the
posts I write in siddhant.codes. The goal was to take
the yaml frontmatter from my posts, generate a png format image and store it in
a certain directory, preferably ./src/assets/og/{og_output}.png.
The Solution
I created this cli program that does only one job from requirements stated above. It creates a beautiful png image based on the args passed to it.
Installation
The only way to get this program on your computer is by running:
go get github.com/siddhantk232/og-image-generatorThis should work on windows computer also but I haven't tested it.
Usage
Run og-image-generator with no args and it will generate a sample png file
named out.png in the current directory.
This is intended to be used as a git hook. See the sample-git-hook.sh
for an example.
