Glimmer VM is a low-level, flexible rendering pipeline written in TypeScript that builds live DOM from Handlebars templates and cheaply updates it when data changes. It is the core rendering engine behind Ember.js, whose packages have since merged into ember-source.

Use cases

• render handlebars templates into live dom
• build a reactive rendering engine for a javascript framework
• incrementally update dom when data changes
• understand or contribute to ember's rendering internals
• compile handlebars templates to efficient bytecode

When to choose

• you are working on ember.js internals or its rendering pipeline
• you need a low-level handlebars-based rendering engine and can maintain it yourself

When to avoid

• you want an actively maintained standalone library - the repo is archived and merged into ember.js
• you need a full frontend framework rather than a rendering pipeline
• you prefer non-handlebars template syntax
