How Codevre Works
Frontend Virtual File System (VFS)
Your entire project lives and operates directly within your browser! This client-side approach eliminates constant server round-trips for file access, making Codevre incredibly responsive.
Custom Virtual Runtime Engine
Our Virtual Runtime Engine (VRE) compiles your code instantly, directly in the browser. This means real-time feedback and execution, speeding up your development loop dramatically.
Seamless, Secure Sandboxing
For secure execution, your entire VFS is packaged and sent to a dedicated, isolated URL. This method allows robust sandboxing without heavy server-side processing or slow web containers.
Dynamic Module Resolution
Codevre handles complex module imports on the fly. We instantly generate runtime import maps, ensuring modules are correctly resolved directly in the browser for any project.
Bundling with esbuild
Codevre supports fully customizable builds through direct integration with esbuild.
Define your own build process by creating an esbuild.config.cjs file.
With support for one-click builds, automatic bundling on code execution, and a
virtualized
fs environment,
Codevre gives you full control over how your projects are compiled and optimized right
in the
browser.
Zero Runtime Costs, Minimal Overhead
Your code execution happens entirely on your device. The only server interactions are for loading or saving projects. This means **zero runtime compute costs** for your projects, making Codevre more affordable and efficient than solutions relying on server-based environments. Our primary cost is just storage.
