To specify your python version, you also need a runtime.txt file - unless you are using the default Python runtime version.Ĭurrent default Python Runtime: Python 3.6.7Īlternatively, you can provide a setup.py file, or a Pipfile. Remote: Procfile declares types -> (none)Ī requirements.txt must be present at the root of your application's repository to deploy. Remote: Installing collected packages: Werkzeug, click, MarkupSafe, Jinja2, itsdangerous, flask Remote: Collecting flask (from -r /tmp/build_c2c067ef79ff14c9bf1aed6796f9ed1f/requirements.txt (line 1)) Remote: -> Installing requirements with pip My-application requirements.txt runtime.txt solved it as well by adding setTimeOut to a promise but this just didn’t seem clean to me. unfortunately, some of the external modules aren’t asynchronous. My webapp must work on asynchronous process. solved it but it wasn’t as clean as i wanted.

Heroku request timeout : this was a nightmare to me since my app takes a long time to process.

The performance : wasn’t as i wanted and could’ve been much better if i wasn’t on the free plan.

Since i’m on the free plan of Heroku I've got into some problems and had me on limits : const ffmpeg = require('fluent-ffmpeg') const screenShotGen = async (filename,count = '13') => 6- Showing the results :Īnd now it’s time to show the results, for this i used react tiny link. 2- Generating the screenshots :įor this i used ffmpeg ( used the ffmpeg buildpack on heroku), and the node fluent ffmpeg. Then the video gets checked to make sure that the uploaded file is a video, and to make sure that the video’s size isn’t more than 200 mb. on the server side, i used express file upload. Then, i used node download helper to download the video using that link.Ģ-Upload the video from your own device : you press choose file and then you select the video and then the video gets sent as formData.

The link gets sent to the server as post request. 1- Paste the direct link to the video and press search button.
