Docker single executable / memory consumption

[predaytor]

Is it possible to reduce memory consumption with Fresh 2.0? Currently deployed on fly.io on a 1024MB machine, while a similar application on Node.js consumes around 190-220MB of RAM. Maybe we can create a single executable and get rid of typescript transpilation at runtime? Very thanks.

FROM denoland/deno:debian

WORKDIR /app

COPY . .

RUN deno task build

EXPOSE 80

CMD ["run", "-A", "main.ts"]

Will this be possible with the release of Deno 2.1.0?

denoland/deno#26939

To include files or directories in the executable, specify them via the --include <path> flag.

deno compile --include names.csv --include data main.ts

Then read the file relative to the directory path of the current module via import.meta.dirname:

// main.ts
const names = Deno.readTextFileSync(import.meta.dirname + "/names.csv");
const dataFiles = Deno.readDirSync(import.meta.dirname + "/data");

// use names and dataFiles here

Note this currently only works for files on the file system and not remote
files.
