workspace import

I have a vsc root-level settings.json file

{
    "deno.enable": true,
    "deno.enablePaths": [
        "./"
    ],
}

{
    "deno.enable": true,
    "deno.enablePaths": [
        "./"
    ],
}

I want to be able to use the following inside of the deno projects inside the directory

{
    "imports": {
        "$std/":"https://deno.land/[email protected]/"
    }
}

{
    "imports": {
        "$std/":"https://deno.land/[email protected]/"
    }
}

but I am getting the following Relative import path "$std/assert/mod.ts" not prefixed with / or ./ or ../deno(import-prefix-missing)

Distroless Docker image fails with `libc.so: cannot open shared object file: No such file`

I am building a 1:1 with a Node project using the same base for a docker image distroless/cc. Both projects use the same external dependency pulled from npm called libsql however the Deno project seems to fail with the following error

libc.so: cannot open shared object file: No such file or directory

libc.so: cannot open shared object file: No such file or directory

I am unsure where to direct this issue as I can see that the container does include a file under /lib/x86_64-linux-gnu directory. Here is my current dockerfile

ARG DENO_VERSION=1.37.2

FROM denoland/deno:${DENO_VERSION} AS build
WORKDIR /app

USER deno

COPY deno.* deps.ts ./
RUN deno cache deps.ts

ADD . .

RUN deno cache cmd/www/main.ts

# ? --------------------------------

# FROM gcr.io/distroless/cc AS final
FROM denoland/deno:distroless-${DENO_VERSION} AS final
WORKDIR /app

COPY --from=build /deno-dir /deno-dir
COPY . .

CMD ["run", "-A", "--unstable", "cmd/www/main.ts"]

EXPOSE 8000

ARG DENO_VERSION=1.37.2

FROM denoland/deno:${DENO_VERSION} AS build
WORKDIR /app

USER deno

COPY deno.* deps.ts ./
RUN deno cache deps.ts

ADD . .

RUN deno cache cmd/www/main.ts

# ? --------------------------------

# FROM gcr.io/distroless/cc AS final
FROM denoland/deno:distroless-${DENO_VERSION} AS final
WORKDIR /app

COPY --from=build /deno-dir /deno-dir
COPY . .

CMD ["run", "-A", "--unstable", "cmd/www/main.ts"]

EXPOSE 8000

Any suggestions?

Deploy says Worker not defined for ESBuild (wasm.js)

@Deno AI Helper I am having trouble understanding how to get the esbuilder to work on Deno Deploy, using write: false here is what my conifg looks like currently

const result = await esbuild.build({
    entryPoints: ["./hello_world.ts"],
    platform: "browser",
    target: ["chrome99", "firefox99", "safari15"],
    format: "esm",
    bundle: true,
    minify: true,
    absWorkingDir: Deno.cwd(),
    outdir: ".",
    write: false,
    metafile: false,
    // @ts-ignore been updated to v0.19.2
    plugins: [...denoPlugins()],
});

console.log(result.outputFiles)

const result = await esbuild.build({
    entryPoints: ["./hello_world.ts"],
    platform: "browser",
    target: ["chrome99", "firefox99", "safari15"],
    format: "esm",
    bundle: true,
    minify: true,
    absWorkingDir: Deno.cwd(),
    outdir: ".",
    write: false,
    metafile: false,
    // @ts-ignore been updated to v0.19.2
    plugins: [...denoPlugins()],
});

console.log(result.outputFiles)

The error seems to suggest that the Worker is not defined even though I am using the wasm version of [email protected]

Does calling `bundle` inside a handler make sense?

hey all I wanted to understand if this is smart to do. I am using the cacheRoot option and wanted to know if that affects the way the code is executed here. As its being called inside a handler I am unsure if this is going to compile everytime or does the cacheRoot option speed that up?

app.get("/index.js", async (c) => {
  const { code } = await bundle(
    new URL("./components/mod.ts", import.meta.url),
    { cacheRoot: Deno.cwd() },
  );
  return c.text(code);
});

app.get("/index.js", async (c) => {
  const { code } = await bundle(
    new URL("./components/mod.ts", import.meta.url),
    { cacheRoot: Deno.cwd() },
  );
  return c.text(code);
});

extension method returning undefined for `text/plain`

Given the following:

console.log(
    "text/plain",
    extension("text/plain"),
    extensionsByType("text/plain"),
    parseMediaType("text/plain"),
    [...extensions.entries()]
);

console.log(
    "text/plain",
    extension("text/plain"),
    extensionsByType("text/plain"),
    parseMediaType("text/plain"),
    [...extensions.entries()]
);

I seem to get the result

text/plain undefined undefined [ "text/plain", undefined ] []

text/plain undefined undefined [ "text/plain", undefined ] []

Am I missing something?

denodrivers/sqlite and deno-sqlit behave different with multiple `?` args

I wanted to understand why these return different results

Deno.test("DB()", (_) => {
    // deno-sqlite
    const db = new DB(":memory:");

    const stmt = db.prepareQuery("SELECT ?, ?");

    const rs = stmt.all(["one", "two"]);
    //    ^? [ [ "one", "two" ] ]

    stmt.finalize();

    db.close();
});

Deno.test("Database() ? arguments", (_) => {
    // denodrivers/sqlite
    const db = new Database(":memory:");

    const stmt = db.prepare("SELECT ?, ?");

    const rs = stmt.all("one", "two");
    //    ^? [ { "?": "two" } ]

    stmt.finalize();
    db.close();
});

Deno.test("Database() : arguments", (_) => {
    // denodrivers/sqlite
    const db = new Database(":memory:");

    const stmt = db.prepare("SELECT :one, :two");

    const rs = stmt.all({ one: "one", two: "two" });
    //    ^? [ { ":one": "one", ":two": "two" } ]
    console.log(rs);

    stmt.finalize();
    db.close();
});

Deno.test("DB()", (_) => {
    // deno-sqlite
    const db = new DB(":memory:");

    const stmt = db.prepareQuery("SELECT ?, ?");

    const rs = stmt.all(["one", "two"]);
    //    ^? [ [ "one", "two" ] ]

    stmt.finalize();

    db.close();
});

Deno.test("Database() ? arguments", (_) => {
    // denodrivers/sqlite
    const db = new Database(":memory:");

    const stmt = db.prepare("SELECT ?, ?");

    const rs = stmt.all("one", "two");
    //    ^? [ { "?": "two" } ]

    stmt.finalize();
    db.close();
});

Deno.test("Database() : arguments", (_) => {
    // denodrivers/sqlite
    const db = new Database(":memory:");

    const stmt = db.prepare("SELECT :one, :two");

    const rs = stmt.all({ one: "one", two: "two" });
    //    ^? [ { ":one": "one", ":two": "two" } ]
    console.log(rs);

    stmt.finalize();
    db.close();
});

If I replace the denodrivers prepare statement to use named args I get correctly two values so unsure which method is needed to be called to get both to behave consistently
