data from the command-line

[ahl]

Is your feature request related to a problem? Please describe.
I am running eleventy in development and from netlify. I'd like the ability to inject some data from the environment into my templates.

Describe the solution you'd like
A command line option to the eleventy command to either specify a file with data (json/js/etc) or specify k/v pairs on the command line.

e.g. eleventy --data baseUrl=$DEPLOY_PRIMEURL

Describe alternatives you've considered
Here's how I worked around it with javascript data in a file I called _data/site.json:

module.exports = function() {
  return new Promise((resolve, reject) => {
    var url = process.env.CONTEXT == 'production' ?
      process.env.URL :
      process.env.DEPLOY_PRIME_URL;
    resolve({
      "baseUrl": url || "http://localhost:8080"
    });
  });
};

What would block you from using environment variables here?

@Ryuno-Ki I must not be understanding your question because my workaround is to use environment variables, but it seems at best inelegant.

Nothing would block me from using environment variables. My suggestion is that it would be useful to allow data overrides to be specified at the command line.

Ah I’m not sure about this one, hmm. I will put it into the queue but this seems pretty limited compared to the workaround you’re using!
