Seq Playground

Playground for compiling and running Seq code remotely.

Requirements

• Python 3
• Flask
• Flask-CORS
• Docker

Usage

1. Build Docker image:

   docker build -t seq-playground .

2. Run Flask app; e.g.

   gunicorn -w 4 -b 157.230.95.210:8000 seq-playground:app

3. Send a POST request to /seq_exec endpoint; e.g.

   curl -i -X POST -H 'Content-Type: application/json' -d '{"code": "print 2 + 2"}' http://157.230.95.210:8000/seq_exec

JavaScript example

var code = 'print 2 + 2';
$.ajax({
    url: 'http://157.230.95.210:8000/seq_exec',
    dataType: 'text',
    type: 'post',
    contentType: 'application/json',
    data: JSON.stringify({'code': code}),
    processData: false,
    success: function(data, textStatus, jQxhr) {
        // remove error code ANSI colors
        var dataClean =
          data.replace(/[\u001b\u009b][[()#;?]*(?:[0-9]{1,4}(?:;[0-9]{0,4})*)?[0-9A-ORZcf-nqry=><]/g, '');
        $('#result').html(dataClean);
    },
    error: function(jqXhr, textStatus, errorThrown) {
        $('#result').html('error: could not communicate with execution server');
    }
});
