This implements the configuration mechanism I described in #2621. The heavy lifting is delegated to [node-config](https://github.com/lorenwest/node-config) with a minor assist from [dotenv](https://github.com/motdotla/dotenv).
`private/secret.json` has been replaced with environment variables and/or `config/local.yml`. See `doc/server-secrets.md`.
This simplifies and further optimizes text-width computation by computing the entire width table in advance, and serializing it in the style of QuickTextMeasurer (#1390). This entirely removes the need for PDFKit at runtime. This has the advantage of fixing #1305 – more generally: producing the same result everywhere – without having to deploy a copy of Verdana.
The lifting is delegated to these three libraries, which are housed in a monorepo: https://github.com/metabolize/anafanafo
I'd be happy to move it into the badges org if folks want to collaborate on maintaining them.
QuickTextMeasurer took kerning pairs into account, whereas this implementation does not. I was thinking kerning would be a necessary refinement, though this seems to work well enough.
I dropped in a binary-search package to traverse the data structure, in part to conserve space. This causes a moderate performance regression, though there is ample room for improving on that: https://github.com/badges/shields/pull/2311#issuecomment-439182704
* fix: update nodejs version to latest LTS, to fullfill check-node-version. close#1437
* docs: add docker run example without shields.env file, because there is no such file in a repo and container wont start
* fix: docker build project, clean npm and run production mode. close#1373
If Verdana.ttf can't be loaded, the font file pointed by the
FALLBACK_FONT_PATH environment variable will be loaded.
This fixes width computation errors that can occur with non-latin
characters when running with Docker.
