Refactoring javascript string config-CodePudding

I have a huge string config in a file and i want to refactor it to have intelisense.
Note there are also variables in it, so using a function would be the best option.
The result of the return function should be exactly what's inside the config string.

  const existingConfig = `
  var configOptions =  {
    enableProp: true,
    style: "plain",
    onReady: function() {
        return true
    }
  }
    `;

I tried something like:

  const newConfig = (val) => {
    return {
      enableProp: true,
      style: val,
      onReady: function() {
        return true
      }
    };
  };
  const res = JSON.stringify(newConfig());

Any ideas?

CodePudding user response：

what about

let configString = (() => {

  var configOptions =  {
    enableProp: true,
    style: "plain",
    onReady: function() {
        return true
    }
  };

}).toString();

configString = configString.slice(
  configString.indexOf("{") 1, 
  configString.lastIndexOf("}")
);

console.log(configString);

You could also do .toString().replace(/^.*?\{|\}.*?$/g, ""); but I don't like it, because the }.*$ part could mean a lot of backtracking. I'm not sure how well it behaves with 700 lines of JS probably containing a lot of }.
