Designing “least-authority” JavaScript apps

Learn the problems and solutions of combining "trusted" and "untrusted" JavaScript. We introduce secure dialects of JavaScript and practical tools that are available to help contain third-party dependencies.

Schedule TBD
Abstract

How can trusted and untrusted JavaScript modules safely co-exist within the same application runtime? Maybe your app loads third-party scripts as “plug-ins”, or maybe the functionality of your app itself is built from third-party modules using a package manager. Dealing with untrusted code is more common than you may think. We discuss how modules can be “isolated” from one another, independent of whether you’re using JS in front-end or back-end applications. We introduce secure dialects of JavaScript and practical tools that are available to help contain third-party dependencies.

Key takeaway

Learn how to get "trusted" and "untrusted" JavaScript to safely co-exist in your app.
