Can this library be used in ES without webpack? #72
Comments
|
There is in node-figlet (https://github.com/patorjk/figlet.js/blob/master/lib/node-figlet.js). That's what package.json points to (for the "main" prop). Also, at the bottom of the figlet file, there is an export statement. What kind of changes are you thinking of? What would be the use case? I'm all for updating the package if it makes it easier for something, as long as it maintains its backward compatibility. |

@patorjk close, but it's an exports statement, as opposed to export. The story is like this, when nodejs was born, the browsers did not have a module system yet. And suddenly npm created a big ecosystem that potentially could benefit the web dev 10 years ago. However, at the time, in order for browsers to use a 3rd party library, the library has to inject itself into the The good part of webpack is help to bundle a web app, but the evil part webpack is to hinder the incentive of migrating the old node package system to ES module system, like yours. So that's why you could see lodash and lodash-es co-exist. Good thing is node has started to support ES syntax so that's the start of the death of the require syntax. So I think it may make sense to create a new file called figlet-es.js which will be usable in modern browsers natively. |

Is there a workaround for this? I can't seem to import |
Yes. The work around is stop using Node and start using Deno. You can reverse engineer this entire library with ChatGPT in 4 hours and somehow, people are still using God Forsaken Webpack.Allow me to illustrate:
// types.ts
export type AsciiFont = {
height: number;
chars: Record<string, string[]>;
}
// Define code languages and script languages that will have specific comment styles
export const codeLanguages: string[] = [
"js",
"ts",
"go",
"rust",
"c",
"java",

"sql"

Object.freeze(codeLanguages);
// Define script languages that will have specific comment styles

I don't see any export keyword in the figlet.js. I wonder if you can make a change so we can use it in native ES code? Thanks.
