Structure microservices

Hi, how would you structure a Deno microservice repository with a good developer experience (good debugging, ..., communication using message brokers)? Do you have any example?

Running deno in distroless image does not work well

Hey, I have the following Dockerfile:

FROM node:lts AS build
WORKDIR /app
COPY .npmrc package.json pnpm-lock.yaml ./
RUN npm install -g pnpm \
    && pnpm fetch --prod
COPY . ./
RUN pnpm install -r --offline --prod \
    && pnpm build

# Run
FROM denoland/deno:distroless-1.34.2
USER deno
COPY --from=build --chown=deno:deno /app/dist/ /app/
WORKDIR /app/server
ENV HOST=0.0.0.0
ENV Port=3000
EXPOSE 3000
HEALTHCHECK --interval=30s --timeout=30s --start-period=5s --retries=3 CMD curl --fail http://localhost:3000 || exit 1 
CMD ["run", "--allow-net", "--allow-read", "--allow-env", "entry.mjs"]

FROM node:lts AS build
WORKDIR /app
COPY .npmrc package.json pnpm-lock.yaml ./
RUN npm install -g pnpm \
    && pnpm fetch --prod
COPY . ./
RUN pnpm install -r --offline --prod \
    && pnpm build

# Run
FROM denoland/deno:distroless-1.34.2
USER deno
COPY --from=build --chown=deno:deno /app/dist/ /app/
WORKDIR /app/server
ENV HOST=0.0.0.0
ENV Port=3000
EXPOSE 3000
HEALTHCHECK --interval=30s --timeout=30s --start-period=5s --retries=3 CMD curl --fail http://localhost:3000 || exit 1 
CMD ["run", "--allow-net", "--allow-read", "--allow-env", "entry.mjs"]

But for some reason I get some error:

$ docker run asciity:0.1.0 -p 3000:3000
docker: Error response from daemon: unable to find user deno: no matching entries in passwd file.

$ docker run asciity:0.1.0 -p 3000:3000
docker: Error response from daemon: unable to find user deno: no matching entries in passwd file.

. Do you have some idea to fix it?

Static compilation of deno modules

Is there a way to statically compile libraries into the .js bundle instead of dynamically retrieving them from deno.land. The point is that I would like to test the Boa engine in the Deno environment and so the libraries are interfering. Of course the Deno internals have to be implemented afterwards. So that, for example, from the following code:

import { fetch } from "https://deno.land/x/file_fetch@0.2.0/mod.ts";

import { fetch } from "https://deno.land/x/file_fetch@0.2.0/mod.ts";

becomes: the compiled code of https://github.com/lucacasonato/deno_local_file_fetch/blob/main/mod.ts something like:

async function fetch(
  input: string | Request | URL,
  init?: RequestInit,
): Promise<Response> {
  // impl
}

async function fetch(
  input: string | Request | URL,
  init?: RequestInit,
): Promise<Response> {
  // impl
}

[resolved] CI failure TS2684

Hey, I'm currently working on a pull request for the Astro project. Unfortunately the CI doesn't like my code despite the latest Deno version (1.26.1). Does anyone know what the reason is and can possibly give me a solution? GitHub Actions run: https://github.com/withastro/astro/actions/runs/3200178618/jobs/5226807106.

error: TS2694 [ERROR]: Namespace 'Deno' has no exported member 'PermissionOptions'.

error: TS2694 [ERROR]: Namespace 'Deno' has no exported member 'PermissionOptions'.

export const defaultTestPermissions: Deno.PermissionOptions = {
    read: true,
    net: true,
    run: true,
    env: true
};
