deno-proc

Abstractions for running processes in Deno.

This is still very early. Things are going to change. A lot. Functionality is limited. The API is unstable.

Deno has all the right parts for working with processes, but I really want something that is a better version of what I get in bash scripts. I want stdin and stdout pipes, decent default error handling, and minimal need to manually close things. I want all this to work with a fluent API.

deno doc -q https://deno.land/x/proc/mod.ts

stdout from a process as lines

for await (const line of new Proc({ cmd: ["ls", "-la"] }).stdoutLines()) {
  console.log(line);
}

pipe stdout to stdin

const fileCount = await first(
  run({ cmd: ["ls", "-1"] })
    .pipe(run({ cmd: ["wc", "-l"] }))
    .stdoutLines(),
);

console.info(
  `Total number of files and folders in ${resolve(".")} is ${parseInt(fileCount!, 10)}.`,
);
