Browser Quick Start error in code pen

[tomByrer]

I decided to try to try my hand at doing the tutorial in CodePen: https://codepen.io/tomByrer/pen/gKEvYM But I get Unexpected identifier error for await pfs.mkdir(dir);

I don't think it is my CDN choice: https://codepen.io/tomByrer/pen/wXOyBd

Both Fx Quantum 61 & Chrome 67.0.3396.87 Linux

Ah. New to async/await are you? They have a sneaky catch... you can't use await at the top level; it has to be inside an async function. Here's a version that would work:

(async () => {
    window.dir = 'tutorial'
    console.log(dir);
    await pfs.mkdir(dir);
    // Behold - it is empty!
    await pfs.readdir(dir);
})()

But this is so annoying that most examples / tutorials will leave out the (implied) wrapper function. Top-level await is already supported in the Chrome debugger console, and will probably be added to the spec soon.

Ah. Sadly this is not the only obstacle you face in this Code Pen! Sadly https://cdn.jsdelivr.net/npm/pify@3.0.0/index.js delivers a Node-only version of the module. (Which is why in my example I ran it through the browserify CDN... which has sadly been slow and crashy of late.) You can use the version of pify hosted on the website though: https://isomorphic-git.github.io/js/pify.js

You're also using the Node version of isomorphic-git, which definitely won't work. You can use this one: https://cdn.jsdelivr.net/npm/isomorphic-git@0.19.11/dist/bundle.umd.min.js

Lastly, you're using the 1.x version of BrowserFS instead of the 2.x version. It looks like jsDelivr doesn't deliver 2.0. You can try https://cdnjs.cloudflare.com/ajax/libs/BrowserFS/2.0.0/browserfs.min.js instead.

And... huh I'm still getting an error,

pen.js:10 Uncaught TypeError: BrowserFS.configure(...) is not a function

Gimme a moment. 🤔
