NOT ON THE CURRENT EDITION
This blip is not on the current edition of the Radar. If it was on one of the last few editions it is likely that it is still relevant. If the blip is older it might no longer be relevant and our assessment might be different today. Unfortunately, we simply don't have the bandwidth to continuously review blips from previous editions of the RadarUnderstand more

Trial?

single-spa is a JavaScript framework for bringing together multiple micro frontends in a single front-end application. Although we advise against micro frontend anarchy, the use of micro frontends as an excuse to mix and match multiple frameworks, single-spa supports just that. We understand that there are legitimate scenarios such as upgrading to a new revision of a framework across multiple micro frontends where integration across multiple frameworks is necessary. single-spa has been a go-to framework for micro frontend integration for our teams, and they're finding it to work well with SystemJS and managing different versions of a single dependency.

Assess?

single-spa is a JavaScript metaframework that allows us to build micro frontends using different frameworks that can coexist in a single application. In general, we don't recommend using more than one framework for an application, but there are times when we can't avoid doing so. For instance, single-spa can be quite useful when you're working with a legacy application and you want to experiment by developing a new feature, with either a new version of the existing framework or a completely different one. Given the short life span of many JavaScript frameworks, we see a need for a solution that would allow for future framework changes and localized experimentation, without affecting the entire application. single-spa seems to be a good start in that direction.
