Flask + Vue.js Web Application Template

Live Demo


If this setup is not what you are looking for, here are some similar projects:

Old Template

This template was updated to use a flatter folder structure and use yarn instead of npm. You can now run yarn serve as well as other yarn commands from the template root directory. The old template will be kept in the npm-template branch but will not be maintained.

Template Structure

The template uses Flask & Flask-RestPlus to create a minimal REST style API, and let's VueJs + vue-cli handle the front end and asset pipline. Data from the python server to the Vue application is passed by making Ajax requests.

Application Structure

Rest Api

The Api is served using a Flask blueprint at /api/ using Flask RestPlus class-based resource routing.

Client Application

A Flask view is used to serve the index.html as an entry point into the Vue app at the endpoint /.

The template uses vue-cli 3 and assumes Vue Cli & Webpack will manage front-end resources and assets, so it does overwrite template delimiter.

The Vue instance is preconfigured with Filters, Vue-Router, Vuex; each of these can easilly removed if they are not desired.

Before you start

Before getting started, you should have the following installed and running:

  • [X] Yarn - instructions
  • [X] Vue Cli 3 - instructions
  • [X] Python 3
  • [X] Pipenv (optional)
  • [X] Heroku Cli (if deploying to Heroku)
Template and Dependencies
  • Clone this repository:

     $ git clone
  • Setup virtual environment, install dependencies, and activate it:

     $ pipenv install --dev
     $ pipenv shell
  • Install JS dependencies

     $ yarn install

Development Server

Run Flask Api development server:

$ python

From another tab in the same directory, start the webpack dev server:

$ yarn serve

The Vuejs application will be served from localhost:8080 and the Flask Api and static files will be served from localhost:5000.

The dual dev-server setup allows you to take advantage of webpack's development server with hot module replacement.

Proxy config in vue.config.js is used to route the requests back to Flask's Api on port 5000.

If you would rather run a single dev server, you can run Flask's development server only on :5000, but you have to build build the Vue app first and the page will not reload on changes.

$ yarn build
$ python

Production Server

This template is configured to work with Heroku + Gunicorn and it's pre-configured to have Heroku build the application before releasing it.

JS Build Process

Heroku's nodejs buidlpack will handle install for all the dependencies from the packages.json file. It will then trigger the postinstall command which calls yarn build. This will create the bundled dist folder which will be served by whitenoise.

Python Build Process

The python buildpack will detect the Pipfile and install all the python dependencies.

Production Sever Setup

Here are the commands we need to run to get things setup on the Heroku side:

$ heroku apps:create flask-vuejs-template-demo
$ heroku git:remote --app flask-vuejs-template-demo
$ heroku buildpacks:add --index 1 heroku/nodejs
$ heroku buildpacks:add --index 2 heroku/python
$ heroku config:set FLASK_ENV=production
$ heroku config:set FLASK_SECRET=SuperSecretKey

$ git push heroku
