A significant part of the course is devoted not to Flask itself (it’s tiny), but to third-party libraries and tools often used in Flask projects. Chargify will keep sending the webhook if it encounters any problems in delivery or not recieving a 202 response in time. So this section just make sure we only process each webhook once, just in case anything goes wrong and it gets sent again.

This snippet copies the requirements/common.txt file from your system environment into the image. We then upgrade pip and install the requirements in the requirements/common.txt file. This means we’re only installing the dependencies we need to run your service and not installing dependencies used only for development . Of course, if you’re updating the routes as in previous sections in your API, you need to make sure to update the test suite to capture these changes. In fact, if you’re being good and following a Test Driven Development workflow, you should add tests to the tests/test_api.py before you write any extensions to your core API code. The tests/test_api.py file is set up to make writing tests for your API that little bit easier.

Memory and CPU limits

That is when I realized that what I was really interested in was to build and improve those systems myself rather than just analysing them and I started to learn programming on my own. When looking for my next contract I was offered a permanent position at Close Brothers and that was the opportunity for me to settle down. The role has proved to be very interesting as I was exposed to high-profile property developments, energy assets financing and even Barclays Premier League football transfers. I aim to be an expert in financial data and quantitative analysis using my experience in Python and my knowledge of risk analysis. I have hands-on experience in data engineering, data modelling, database design which I would like to apply to large financial datasets. I am deeply passionate about programming because it is both creative and intellectually stimulating.

We will show you it is simple, flexible, and modular, leading to an enjoyable development experience. Ideally, you are a Software Engineer/DevOps with proven experience on building Cloud-based applications/APIs , who will help us enhance our current API system for audio-driven video generation. Whilst reading a book, javascript records the page number the user is on and sends this information to update the database.

Having an understanding of Docker will come in handy if you follow the deployment steps at the end of this post. Additionally, for this post I’m particularly focussing on Flask apps developed for the purpose of providing APIs as web services. This is a fundamental use-case for many software professionals, and it’s also increasingly relevant to many Machine Learning practitioners too. Plus it is something that can be a bit bewildering to new-comers to the software world. This post is therefore aimed at giving a simple but solid ‘production-ready’ Flask service template for you to build upon, and to share some rationale for the structure I’ve provided. I’ve also given a few basic steps to get the template project deployed to Google Cloud Run too.

@shared_task will create an independent instance of the task for each app, making task reusable, so it’s important to specify this decorator for time-consuming tasks. The function will create a new object for each crawled row and sleep a few seconds to avoid blocking the database. Doing so can be the difference between having a neat, performant API, and spaghettified, spluttering mess of an API. I’d also like to emphasise that this is far from all there is to Flask, but I think these are few areas that you might find particularly useful for basic APIs. Now that we’ve considered some basic functionalities to have basic endpoints created with Flask, let’s create a better project structure and documentation for our endpoints.

A mix of programming skills and financial knowledge

Joined the data team at Resolver to help the effective integration of multiple data sources into the data pipeline to database, analytics, and machine-learning data repositories. The Vertical Pod Autoscaler paired with metrics server is an excellent combo to remove any sort of guesstimation from choosing requests and limits. You just set requests and limits for a brand new application even if you were not familiar with it. The real-time graph shows the requests per second received by the app, as well as failure rate, response codes, etc.

Nevertheless, any person should be able to have the application 🆙 and 🏃 after following this tutorial. If you have any questions, please feel free to get in touch, and we will do our best to help. If you already know the basics of Flask and you are interested in how to design, architect and build an API platform, this is the course for you. An endorsed course is a skills based course which has been checked over and approved by an independent awarding body. Endorsed courses are not regulated so do not result in a qualification – however, the student can usually purchase a certificate showing the awarding body’s logo if they wish. Certain awarding bodies – such as Quality Licence Scheme and TQUK – have developed endorsement schemes as a way to help students select the best skills based courses for them. Welcome to one of the best resources online on creating REST APIs.

However, you can keep all of your code together in a single file (e.g. in api/app.py) if you so wish. It stands for ‘Web Server Gateway Interface’, and – in short – it’s a specification defining how a web server can interact with Python applications. Makefile – This file provides a simple mechanism for running useful commands for your project. Gain some insights on the advanced Flask integrations for scaling web applications.

The team was able to learn something new in the end with topics that were interesting but it was only in the last day. There were also more hands on activities than slides which was good. What I like the most about the training is that everything in the course python api design outline is something that will be useful for our projects. The trainer was excellent, He was always ready to answer my questions and share as much knowledge as he could. I preferred the exercise and learning about the nooks and crannies of Python.
