Deno.readDir and Deni.cwd not available when deployed

[AndrewHeaney]

Hi, I am creating a simple blog using pagic and oak with Deno. I can run my code fine locally using deployctl but I get these errors when the code is deployed.

[uncaught oak error]: TypeError - Deno.cwd is not a function

[uncaught oak error]: TypeError - Deno.readDir(...) is not a function or its return value is not async iterable

My code looks as follows:

const app = new Application();
const router = new Router();

router.get("/", async (ctx) => {
  let links = [];
  for await (const dirEntry of Deno.readDir("public")) {
    if (dirEntry.isFile && dirEntry.name.match("^[a-zA-Z]+.[a-zA-Z]+.html$")) {
      console.log(dirEntry);
      links.push(`<a href="${dirEntry.name}">${dirEntry.name}</a>`);
    }
  }

  ctx.response.headers.set("Content-Type", "html");
  ctx.response.body = `
    <h1>Blog</h1>
    <h5>Example blog using Deno</h5>
    <p>Posts:</p>
    ${links}
  `;
});

app.use(router.routes());

// Send static content
app.use(async (context) => {
  await context.send({
    root: `${Deno.cwd()}/public`,
  });
});

addEventListener("fetch", app.fetchEventHandler());

Any help is appreciated.

Hi, @AndrewHeaney :)

Support for Deno.readDir() and Deno.cwd() (You can use import.meta.url as near replacement) is not available on Deploy yet. They should be available in a few weeks. You can refer https://deno.com/deploy/docs/runtime-api for supported APIs.

No problem, thank you for the response. I'll check it out when it becomes available.

Thanks for contributing by opening an issue.

This project is being archived because you can now use deno run to run your Deploy scripts locally: https://deno.com/deploy/docs/running-scripts-locally/. As such, I will close this issue.

If you have feedback about Deno Deploy, please open an issue on this repo: https://github.com/denoland/deploy_feedback
