Deno August Update: more flexible security in 1.36, persistent logs in Deno Deploy, and more

Hot runtime summer is in full swing and with that comes ton of updates! Read on to learn about more granular security controls in Deno 1.36, searchable and filterable logs on Deno Deploy, simplified route components in Fresh 1.3, and more.

Deno 1.36: More flexible security and expanded testing APIs

Deno’s opt-in permission model gives you control over what your (or third-party) code has access to. Until now, you could either grant unfettered access to a feature or configure specific domains or directories with --allow-* .

In Deno 1.36, we introduce the --deny-* family of runtime flags to enable more flexible permissions for your Deno programs.

$ deno run --allow-net --deny-net=api.evil.com mod.ts

Fresh 1.3: simplified route components and more

We’re doing monthly Fresh minor releases! This cycle saw improved documentation, bug fixes, and new features, many thanks to the community.

The big update here is Async Route Components, which removes boilerplate for building simple components.

Before:

interface Data {
  foo: number;
}

export const handler: Handlers<Data> = {
  async GET(req, ctx) {
    const value = await loadFooValue();
    ctx.render({ foo: value });
  },
};

export default function MyPage(props: PageProps<Data>) {
  return <p>foo is: {props.data.foo}</p>;
}

After:

// After
export default async function MyPage(req: Request, ctx: RouteContext) {
  const value = await loadFooValue();
  return <p>foo is: {value}</p>;
}

kvdex is a type-safe, simple Deno KV wrapper with zero third-party dependencies.
This blog post peeks under the Deno hood and is useful if you're interested in building your own JS runtime.
Are you writing an FFI-dependent module? Here’s an in-depth walkthrough on how to publish it to deno.land/x.
