svg-to-image-proxy

⚠️ Deprecated

This package is now deprecated and archived. Shields.io has migrated to squint for SVG to PNG conversion.


backers and sponsors chat version license build code style

Web function to generate PNGs from SVGs. Based on convert-svg-to-png which uses headless Chromium.

The proxy accepts a request for e.g. https://raster.example.com/example.png and translates it to a request for https://other-server.example.com/example.svg. If the path doesn't contain .png, it passes is unchanged, e.g. https://raster.example.com/example to https://other-server.example.com/example.

The query string is also forwarded upstream. Cache headers are forwarded downstream.

The host comes from the BASE_URL environment variable.

Designed for Shields though may be useful for other application as well.

Architecture

Deployment

Runs on Zeit Now.

raster.shields.io production hosting

Staging: https://shields-raster-staging.now.sh/

Production: https://raster.shields.io/

raster.shields.io hosting is provided by:

Pull requests are deployed automatically. Staging is deployed automatically from master. Production is deployed manually for now.

For information about current deploys, see the Now dashboard. See production hosting for a list of maintainers with access.

raster.shields.io is configured in the Shields Cloudflare as a CNAME for alias.zeit.co with traffic configured not to pass through Cloudflare. That's because it's cached by Now's Smart CDN instead.

Production Deployment

To deploy, run now alias shields-raster-staging.now.sh raster.shields.io. This ships the current staging build to production.

To setup your environment to run now, you'll need to install the CLI, login, and switch to the Shields team.

npm i -g now
now login
now teams switch shields1
