usage

import { Injector } from "template-printer";

// initialize variable types with opening/closing tags
let myInjector = new Injector(
  {
    foo: {
      open: "{{",
      close: "}}",
      transform: function(value, cb){ // optional transformation callback
        // transform value
        cb(value);
      }
    }
    /* ... more variable types ... */
  }
);

// set or override handler for variable type foo
myInjector.setHandler("foo", function(value, cb){
  // transform value
  cb(value.toUpperCase());
})

let text = "tacos are so foo {{foo}}";

// inject transformed data into text
myInjector
  .InjectVariables(text, {
    foo: "bar"
  })
  .then(output => {
    console.log(output); // <- "tacos are so foo BAR"
  });

To print text/html content:

import { PrintToIframe } from "template-printer";

// spawns print dialg with specified dimensions in inches (4in x 6in)
PrintToIframe("tacos are so foo bar", 4, 6);

Altogether:

import { Injector, PrintToIframe } from "template-printer";

let myInjector = new Injector();

// "text" is one of the default variable types
// here I'm overriding the existing transformation function
myInjector.setHandler("text", function(value, cb){
  cb(value.toUpperCase());
});

let text = "tacos are so foo {{foo}}";

myInjector
  .InjectVariables(text, {
    foo: "bar"
  })
  .then(output => {

    // print injected/transformed content to a 4in x 6in page.
    PrintToIframe(output, 4, 6);
  });
