Build a web page scraping and testing service using GraphQL and Playwright.
In my previous article, I walked through with you on developing serverless APIs to test web pages under different resolutions using
Puppeteer. In this article let’s use
Playwright, which is a similar library to perform web browser automation.
Playwright is a library available in Node.js, Python, and Java to automate
WebKit with a single API. It is built to enable cross-browser web automation that is ever-green, capable, reliable, and fast.
Playwright and browser binaries for
Playwright requires Python 3.7+.
Use Flask AppBuilder to develop CRUD REST APIs.
In this article, let’s use Flask to build RESTful APIs to create, read, update and delete (CRUD) records in a database table. Specifically, I will use Flask + Flask AppBuilder to build the APIs in 5 minutes.
Let’s install the
flask-appbuilder library. I also install
python-dotenv in order to use a
.env file as my configuration file.
$ pip install flask-appbuilder python-dotenv
Using Vim/Neovim to manage your notes and to-do list.
Comparing to Vim/Neovim, one of the great features of Emacs is Org Mode. Org Mode is for keeping notes, maintaining to-do lists, planning projects, authoring documents, computational notebooks, literate programming, and more — in a fast and effective plain-text system.
In this article let’s go through the available options for Vim/Neovim for taking notes and managing to-do lists.
This is one of the most popular options we have for Vim/Neovim. Combining this with
glow.nvim which I mentioned in my previous article makes writing a Markdown document extremely easy.
VimWiki, you can:
New Neovim plugins to improve development workflow and productivity.
In previous articles, I talked about Vim/Neovim plugins to help you code faster, and some of the niche Neovim plugins. In this article let’s go through new Neovim plugins that can improve your development workflow and productivity.
As a developer, we normally need to write documentation in Markdown.
Text to image using Jupyter Notebook on Google Colab.
In one of my articles, I went through code examples on image classification using CLIP and ResNext. In this article let’s go through a few algorithms and libraries which can be used to generate an image from text.
And this is the image generated for the phrase “flying cartoon elephant”.
Managing project-specific settings for Vim/Neovim projects.
I talked about managing multiple databases and projects in my previous articles. On some occasions, you may have a need to manage multiple projects with configurations only specific to the projects.
In this article, let’s explore the available options we have in Vim/Neovim. I will start with the simplest solution and then move on to explore plugins we can use.
If you set the
exrc option in your
init.vim file, Vim/Neovim will execute
.exrc (for both Vim/Neovim),
.nvimrc (Neovim) found in the current directory when Vim/Neovim is started.
Additional features to enhance your LSP experience in Neovim.
In the previous article, I walked through with you how to set up LSP and DAP in Neovim. In this article let’s enhance the LSP experience in Neovim by configuring and setting up additional features.
Just like the previous article, let’s get started by installing the language servers.
If you are using
coc.nvim, normally the language server is installed automatically for you. For Neovim LSP, there are available plugins to automate this process. Here I will go through the manual installation steps.
For Python, let’s install
$ npm install -g…
Managing databases and run SQL statements, all within Vim/Neovim.
In my previous article, I walked through with you how to manage multiple projects within Vim/Neovim. In this article let’s extend this to see how to manage multiple databases.
I am going to use PostgreSQL and MySQL as examples. For this to work, on the client machine you will need to install the database clients.
Yes, you can play games in Emacs!
Continue from my previous article where I walked through with you on setting up LSP and DAP for Emacs, in this article let’s explore gaming in Emacs for amusement and relaxation after a hard day of coding, all within Emacs.
Python application for real time object detection and segmentation.
In previous article I walked through with you on using YOLOv5 for real time object detection. In this article let’s develop a Python application for real time object detection using Detectron2, which is a Facebook AI Research’s next generation software system that implements state-of-the-art object detection algorithms.
