## JavaScriptCore
|
||
|
||
Bun statically links JavaScriptCore (and WebKit) which is LGPL-2 licensed. WebCore files from WebKit are also licensed under LGPL2. Per LGPL2:
|
||
|
||
> (1) If you statically link against an LGPL’d library, you must also provide your application in an object (not necessarily source) format, so that a user has the opportunity to modify the library and relink the application.
|
||
|
||
You can find the patched version of WebKit used by Bun here: <https://github.com/oven-sh/webkit>. If you would like to relink Bun with changes:
|
||
|
||
- `git submodule update --init --recursive`
|
||
- `make jsc`
|
||
- `zig build`
|
||
|
||
This compiles JavaScriptCore, compiles Bun’s `.cpp` bindings for JavaScriptCore (which are the object files using JavaScriptCore) and outputs a new `bun` binary with your changes.
