BarcelonaJS July 2020

Hello everyone, BarcelonaJS is back with our first online meetup. We're waiting for you Tuesday 21st at 7 PM at https://www.youtube.com/watch?v=sc1CfX2-8v0 with the following talks.

Adrian Bolonio - @bolonio

My name is Adrián Bolonio. I'm an experienced Web Team Lead, Frontend Developer, and Web Accessibility (a11y) advocate. I'm from Spain, but since 2012 I've been living and working in Vienna (Austria).

Testing Web Accessibility

When we develop a new web application, we often put a lot of work on the design, on making it beautiful and usable. In other words, we want our web app to be effective, efficient, and satisfying for the user. But a lot of times we don't think about the user experience for people with disabilities, including people with age-related impairments.

For the web, accessibility (a11y ) means that people with disabilities can perceive, understand, navigate, and interact with websites and tools, and that they can contribute equally without barriers." (Source: W3C - Web Accessibility Initiative). Our role as frontend and web developers is to create clear interfaces to make people understand and care about data, independently of their disabilities or impairments, but what we, developers, often forget is to ensure that the code we write follows the Web Content Accessibility Guidelines (WCAG), and the only way to achieve that is testing, either manual or automated.

Automated web a11y tests can free up our QA team from manual testing every part of our application…but…they can't automatically, and magically, make our site accessible.

We should use automated a11y tests as one step of a larger testing process. Don't forget that only 20% to 50% of all accessibility issues can automatically be detected.

I will show you some testing tools, libraries and techniques to increase the a11y test coverage of your code with a simple React application example.

Prisma 2: Modern database tools for Node.js and TypeScript

Working with databases in Node.js/TypeScript can be painful. Traditional ORMs like Sequelize or TypeORM give you a head start but typically fall short once a project grows and becomes more complex. Performance issues and inefficient, generated queries are only a few of the issues an ORM can introduce.

Meet Prisma Client: A lightweight, auto-generated, and type-safe database client.

Prisma takes a new approach to database workflows. The tools are based on the Prisma schema which contains a data model definition. This data model is a declarative representation of your database schema. Prisma Client is auto-generated based on this data model and provides a powerful API to read and write data in your database.
