Ajv Joins OpenJS Foundation as an Incubation Project

By Announcement, Blog, Project Update

Today, Ajv, a JSON Schema validator for both server-side and client-side JavaScript applications, has entered into public incubation at the OpenJS Foundation. Ajv is a key part of the JavaScript ecosystem, used by a large number of web developers with millions of projects depending on it indirectly, via other libraries. 

In addition to becoming an incubating project, Ajv was recently awarded a grant from Mozilla’s Open Source Support (MOSS) program in the “Foundational Technology” track. This grant is continued validation for the important role Ajv plays within the JavaScript ecosystem and will help ensure this work continues. 

“A diverse set of widely used open source projects is why we exist and how our community continues to thrive,” said Robin Ginn, OpenJS Foundation Executive Director. “It’s great when these projects recognize the value of being part of the OpenJS community and benefit from what we are creating here. I’m thrilled to welcome Ajv as an incubation project to the OpenJS Foundation and excited to support its open development among web developers.”

Ajv is a leading JSON Schema validator that is highly specification compliant, supporting JSON Schema drafts 4 to 7. Ajv is also extensible via custom keywords and plugins, and is one of the fastest JSON Schema validators. Additionally, Ajv gets 120 million monthly downloads on npm. Many projects within the OpenJS Foundation use Ajv including webpack, ESlint, and Fastify.

“As CPC chair, I’m really happy that Ajv has become an incubating project at the OpenJS Foundation,” said Joe Sepi, OpenJS Foundation Cross Project Council Chair. “Ajv is an important project within the JavaScript open source space — many of our own projects already use it. This is an important step for Ajv and I, along with the entire CPC, am excited Ajv is taking this step with the OpenJS Foundation.”

“As Ajv’s CPC liaison, the person who helps guide potential projects through the application process, I’m excited for what’s to come for Ajv’s within the OpenJS Foundation,” said Dylan Schiemann, CEO at Living Spec and co-creator of Dojo. “As an incubating project, AJV has a unique opportunity to continue its path toward sustainability and growth. As a user of AJV and an early advocate for JSON Schema, we’re super excited to work with the project and support its growth as part of the OpenJS Foundation.”

“Ajv has become a centerpiece of all data-validation logic in my open-source projects and businesses. It’s spec-compliant, extensible, fast and has amazing support. Ajv joining the OpenJS Foundation will greatly benefit the entire JavaScript ecosystem,” said Gajus Kuizinas, CTO of Contra.

“I’ve been developing Ajv since 2015 and it is nice to see it being so widely used – it would never have happened without almost 100 contributors and a much larger number of users. Both the OpenJS Foundation and Mozilla grant will help Ajv become a permanent fixture in the JavaScript ecosystem – I am really looking forward to the next phase of Ajv development,” said Evgeny Poberezkin, the developer of Ajv.

By joining the OpenJS Foundation, there are multiple organizational and infrastructure areas that will be better supported. Furthermore, Ajv will be able to ensure governance and Code of Conduct enforcement to make sure that Ajv will continue to be stable. Joining will also help Ajv to grow and gain contributors, and potentially help with wider enterprise adoption through greater confidence and overall stability for the project.

As a collaborative project with transparency-first principles, the OpenJS Foundation is happy to welcome Ajv as an incubation project and looks forward to the many successes the project will have within its new home.

Node.js Promise reject use case survey

By Blog, Node.js, Survey

This post was contributed by the Node.js Technical Steering Committee.

The Node.js Project, an impact project of the OpenJS Foundation, handles unhandled rejections by emitting a deprecation warning to stderr. The warning shows the stack where the rejection happened, and states that in future Node.js versions unhandled rejections will result in Node.js exiting with non-zero status code. We intend to remove the deprecation warning, replacing it with a stable behavior which might be different from the one described on the deprecation warning. We’re running a survey to better understand how Node.js users are using Promises and how they are dealing with unhandled rejections today, so we can make an informed decision on how to move forward.

To learn more about what unhandled rejections are and potential issues with it, check out the original post.  Those interested in helping the TSC solve this are encouraged to participate in the survey, which will close on August 24th.

OpenJS World Keynote Fireside Chat: JavaScript Security

By Blog, OpenJS World

During the OpenJS Foundation global conference, OpenJS World, we heard from many inspiring leaders. In this keynote series, we will highlight the key points from the keynote videos. 

In a recent Keynote Fireside Chat, three security experts discussed how open source software, such as JavaScript, is utilized in critical infrastructure and medical devices. Appropriate open source security helps improve cybersecurity and the safety of medical patients. The panel was moderated by Michael Dawson, IBM Community Lead for Node.js. Jessica Wilkerson, a Cyber Policy Advisor for the Food and Drug Administration (FDA), and Adam Baldwin, Sr. Product Manager at GitHub, joined the call to provide their perspectives on JavaScript security.   

Wilkerson started the talk by explaining how open source software has made its way into critical services used by the FDA, including medical devices. The prevalence of open source software, such as JavaScript, requires a more careful consideration of security risks and vulnerabilities. For example, medical devices are submitted with a list of software they are built with, and it is important for developers to understand vulnerabilities in the packages they use — the responsibility does not fall solely on the maintainers. 

All members agreed that in order to make JavaScript more secure it is important for maintainers and bug reporters to work together to solve security issues. When a bug is difficult to identify, tension can develop between vulnerability reporters and maintainers. Ultimately, improving communication and protocol between these two groups can make JavaScript safer.
