William S. Vincent Django APIs + React Django Boston (May
2018) Modern web development with Django Rest Framework & ReactJS
William S. Vincent Who Am I? • Freelance software developer
• Early employee at Quizlet, other startups • Books
William S. Vincent API • Application Programming Interface (API) •
Way for 2 computers to communicate • Need agreed-upon rules (a protocol)
William S. Vincent Why APIs? Pros • Future proof •
Multiple frontends (iOS, Android, web) • Internal or external access Cons • More set up required • User auth is tricky (sessions, tokens, JWT) • JS frameworks change
William S. Vincent What is a web API?
William S. Vincent HTTP • HTTP: Communications protocol for the
web • Web APIs sit “on top” of HTTP • API endpoints: url + available HTTP verbs
William S. Vincent HTTP Verbs Functionality Create Read Update Delete
HTTP Method/Verb POST GET PUT DELETE Rough equivalence between CRUD & HTTP verbs
William S. Vincent HTTP Status Codes Code 2xx 3xx 4xx
5xx Meaning Success (200, 201) Redirection (301) Client error (404) Server error (500)
William S. Vincent API Endpoints • https://mysite.com/api/users # GET returns
collection of all users • https://mysite.com/api/users/<id> # GET returns a single user
William S. Vincent Django APIs
William S. Vincent Building APIs with Django • Multiple packages
available • Django Rest Framework the clear favorite ◦ Easily add to existing Django sites ◦ Complete feature set ◦ Very mature
William S. Vincent Django vs Django API Structure Django template.html
urls.py views.py models.py Django API serializers.py
William S. Vincent Django Rest Framework
William S. Vincent Django + DRF • Add DRF to
existing(!) Django sites • Only need models.py file from regular Django • Write DRF-specific urls.py, views.py, and serializers.py files
William S. Vincent Django Blog 1. Create a new Django
project/app 2. Update models.py and admin.py 3. Add blog posts via Django admin https://github.com/wsvincent/djangoboston-drf-react-blog
William S. Vincent Adding DRF • Install, update settings.py •
Update urls.py (project/app level) • Update views.py
William S. Vincent Serializers • The real “magic” of Django
Rest Framework • Transform models/querysets into JSON • Deserializers transform data from client back into complex data types too
William S. Vincent Serializers # posts/serializers.py from rest_framework import serializers
from . import models class PostSerializer(serializers.ModelSerializer): class Meta: fields = ('id', 'title', 'body',) model = models.Post
William S. Vincent Browsable API
William S. Vincent CORS (Cross-Origin Resource Sharing) • Fundamental security
feature of the web • Allows for cross-domain requests • HTTP Headers added
William S. Vincent What We Didnʼt Cover • Viewsets/Routers •
Authentication/Permissions • Documentation • Tests, Throttling, Pagination, etc.
William S. Vincent Adding React Or Vue, Angular, etc...
William S. Vincent React setup
William S. Vincent Project structure frontend ├── public ├── src
├── App.js backend ├── backend_project ├── settings.py ├── urls.py ├── posts ├── models.py ├── serializers.py ├── views.py ├── urls.py
William S. Vincent App.js • Only need to update one
file! • Endpoint: http://127.0.0.1:8000/api/v1/ • Use map() to display all blog posts
William S. Vincent Conclusion • Add DRF to an existing
Django project • Add CORS headers! • Use create-react-app • Run frontend/backend in two consoles
