Install globally...

npm install -g scramjet-cli

... and use:

$ cat file.log | scr ./my-module > augmented.log

A module that fetches response body from each given url would look like this:

    module.exports = (stream /* assumes StringStream */) => {
        return stream
            .lines()
            .parse(url.parse)
            .map(util.promisify(http.get))
            .catch(e => console.warn("Error in stream", e.stack))
            .map(x => JSON.parse(x));
    };

Full usage:

 Usage: scramjet [-i input] [-o output|-d] [-t StreamClass] [-p plg [-p plg]...] mod1 [mod2] ...
 Options:
 -i --input   input - url to get, file path, empty or '-' for stdin, default: -
 -o --output  output - file path, '@' for print, empty or '-' for stdout, default: -
 -d --display short for -o @, passes the outcome of last module to console.log
 -t --type    stream type, default: StringStream
 -p --plugin  import plugin module (argument for require)
 module       a module that will be passed with the stream and should return a stream
              the module should return an async function that will be called
              the async function will then be awaited and passed to then next
