# Contributing
|
||||
|
||||
There are two pieces to `og-image` that are worth noting before you begin development.
|
||||
|
||||
1. The backend image generator located in [/api/index.ts](https://github.com/vercel/og-image/blob/main/api/index.ts)
|
||||
2. The html/css template used to generate the image is located in [/\_lib/template.ts](https://github.com/vercel/og-image/blob/main/api/_lib/template.ts)
|
||||
3. The frontend inputs located in [/web/index.ts](https://github.com/vercel/og-image/blob/main/web/index.ts)
|
||||
|
||||
Vercel handles [routing](https://github.com/vercel/og-image/blob/main/vercel.json#L6) in an elegant way for us so deployment is easy.
|
||||
|
||||
To start hacking, do the following:
|
||||
|
||||
1. Clone this repo with `git clone https://github.com/vercel/og-image`
|
||||
2. Change directory with `cd og-image`
|
||||
3. Run `yarn` or `npm install` to install all dependencies
|
||||
4. Run locally with `vercel dev` and visit [localhost:3000](http://localhost:3000) (if nothing happens, run `npm install -g vercel`)
|
||||
5. If necessary, edit the `exePath` in [options.ts](https://github.com/vercel/og-image/blob/main/api/_lib/options.ts) to point to your local Chrome executable
|
||||
|
||||
Now you're ready to start local development!
|
||||
|
||||
You can set an environment variable to assist with debugging `export OG_HTML_DEBUG=1`. This will render the image as HTML so you can play around with your browser's dev tools before committing changes to the template.

# Quickstart
|
||||
|
||||
1. To get started: `yarn install`
|
||||
2. To test locally: `yarn start`
|
||||
The local image preview is broken for some reason; but the service works.
|
||||
E.g. try `http://localhost:3000/manifold.png`
|
||||
3. To deploy: push to Github
|
||||
|
||||
For more info, see Contributing.md

# [Open Graph Image as a Service](https://og-image.vercel.app)
|
||||
|
||||
<a href="https://twitter.com/vercel">
|
||||
<img align="right" src="https://og-image.vercel.app/tweet.png" height="300" />
|
||||
</a>
|
||||
|
||||
Serverless service that generates dynamic Open Graph images that you can embed in your `<meta>` tags.
|
||||
|
||||
For each keystroke, headless chromium is used to render an HTML page and take a screenshot of the result which gets cached.
|
||||
|
||||
See the image embedded in the tweet for a real use case.
|
||||
|
||||
## What is an Open Graph Image?
|
||||
|
||||
Have you ever posted a hyperlink to Twitter, Facebook, or Slack and seen an image popup?
|
||||
How did your social network know how to "unfurl" the URL and get an image?
|
||||
The answer is in your `<head>`.
|
||||
|
||||
The [Open Graph protocol](http://ogp.me) says you can put a `<meta>` tag in the `<head>` of a webpage to define this image.
|
||||
|
||||
It looks like the following:
|
||||
|
||||
```html
|
||||
<head>
|
||||
<title>Title</title>
|
||||
<meta property="og:image" content="http://example.com/logo.jpg" />
|
||||
</head>
|
||||
```
|
||||
|
||||
## Why use this service?
|
||||
|
||||
The short answer is that it would take a long time to painstakingly design an image for every single blog post and every single documentation page. And we don't want the exact same image for every blog post because that wouldn't make the article stand out when it was shared to Twitter.
|
||||
|
||||
That's where `og-image.vercel.app` comes in. We can simply pass the title of our blog post to our generator service and it will generate the image for us on the fly!
|
||||
|
||||
It looks like the following:
|
||||
|
||||
```html
|
||||
<head>
|
||||
<title>Hello World</title>
|
||||
<meta
|
||||
property="og:image"
|
||||
content="https://og-image.vercel.app/Hello%20World.png"
|
||||
/>
|
||||
</head>
|
||||
```
|
||||
|
||||
Now try changing the text `Hello%20World` to the title of your choosing and watch the magic happen ✨
|
||||
|
||||
## Deploy your own
|
||||
|
||||
You'll want to fork this repository and deploy your own image generator.
|
||||
|
||||
1. Click the fork button at the top right of GitHub
|
||||
2. Clone the repo to your local machine with `git clone URL_OF_FORKED_REPO_HERE`
|
||||
3. Change directory with `cd og-image`
|
||||
4. Make changes by swapping out images, changing colors, etc (see [contributing](https://github.com/vercel/og-image/blob/main/CONTRIBUTING.md) for more info)
|
||||
5. Remove all configuration inside `vercel.json` besides `rewrites`
|
||||
6. Run locally with `vercel dev` and visit [localhost:3000](http://localhost:3000) (if nothing happens, run `npm install -g vercel`)
|
||||
7. Deploy to the cloud by running `vercel` and you'll get a unique URL
|
||||
8. Connect [Vercel for GitHub](https://vercel.com/github) to automatically deploy each time you `git push` 🚀

Bitstream Vera Fonts Copyright
|
||||
|
||||
The fonts have a generous copyright, allowing derivative works (as
|
||||
long as "Bitstream" or "Vera" are not in the names), and full
|

redistribution (so long as they are not *sold* by themselves). They
|
||||
can be be bundled, redistributed and sold with any software.
|
||||
|
||||
The fonts are distributed under the following copyright:

|
||||
Copyright FAQ
|
||||
=============
|
||||
|
||||
1. I don't understand the resale restriction... What gives?
|
||||
|
||||
Bitstream is giving away these fonts, but wishes to ensure its
|
||||
competitors can't just drop the fonts as is into a font sale system
|
||||
and sell them as is. It seems fair that if Bitstream can't make money
|
||||
from the Bitstream Vera fonts, their competitors should not be able to
|
||||
do so either. You can sell the fonts as part of any software package,
|
||||
however.
|
||||
|
||||
2. I want to package these fonts separately for distribution and
|
||||
sale as part of a larger software package or system. Can I do so?
|
||||
|
||||
Yes. A RPM or Debian package is a "larger software package" to begin
|
||||
with, and you aren't selling them independently by themselves.
|
||||
See 1. above.
|
||||
|
||||
3. Are derivative works allowed?
|
||||
Yes!
|
||||
|
||||
4. Can I change or add to the font(s)?
|
||||
Yes, but you must change the name(s) of the font(s).
|
||||
|
||||
5. Under what terms are derivative works allowed?
|
||||
|
||||
You must change the name(s) of the fonts. This is to ensure the
|
||||
quality of the fonts, both to protect Bitstream and Gnome. We want to
|
||||
ensure that if an application has opened a font specifically of these
|
||||
names, it gets what it expects (though of course, using fontconfig,
|
||||
substitutions could still could have occurred during font
|
||||
opening). You must include the Bitstream copyright. Additional
|
||||
copyrights can be added, as per copyright law. Happy Font Hacking!
|
||||
|
||||
6. If I have improvements for Bitstream Vera, is it possible they might get
|
||||
adopted in future versions?
|
||||
|
||||
Yes. The contract between the Gnome Foundation and Bitstream has
|
||||
provisions for working with Bitstream to ensure quality additions to
|
||||
the Bitstream Vera font family. Please contact us if you have such
|
||||
additions. Note, that in general, we will want such additions for the
|
||||
entire family, not just a single font, and that you'll have to keep
|
||||
both Gnome and Jim Lyles, Vera's designer, happy! To make sense to add
|
||||
glyphs to the font, they must be stylistically in keeping with Vera's
|
||||
design. Vera cannot become a "ransom note" font. Jim Lyles will be
|
||||
providing a document describing the design elements used in Vera, as a
|
||||
guide and aid for people interested in contributing to Vera.
|
||||
|
||||
7. I want to sell a software package that uses these fonts: Can I do so?
|
||||
|
||||
Sure. Bundle the fonts with your software and sell your software
|
||||
with the fonts. That is the intent of the copyright.
|
||||
|
||||
8. If applications have built the names "Bitstream Vera" into them,
|
||||
can I override this somehow to use fonts of my choosing?
|
||||
|
||||
This depends on exact details of the software. Most open source
|
||||
systems and software (e.g., Gnome, KDE, etc.) are now converting to
|
||||
use fontconfig (see www.fontconfig.org) to handle font configuration,
|
||||
selection and substitution; it has provisions for overriding font
|
||||
names and subsituting alternatives. An example is provided by the
|
||||
supplied local.conf file, which chooses the family Bitstream Vera for
|
||||
"sans", "serif" and "monospace". Other software (e.g., the XFree86
|
||||
core server) has other mechanisms for font substitution.

<h2>What is this?</h2>
|
||||
<p>
|
||||
This is a service that generates dynamic
|
||||
<a href="http://ogp.me">Open Graph</a> images that you can embed in
|
||||
your <code><meta></code> tags.
|
||||
</p>
|
||||
<p>
|
||||
For each keystroke, headless chromium is used to render an HTML page
|
||||
and take a screenshot of the result which gets cached.
|
||||
</p>
|
