Build Javet¶

It's quite hard for developers to build Javet successfully for various reasons.

Node.js needs to be built to static libraries.
V8 needs to be built to monolith.
Every OS platform has its own pitfalls which usually make developers frustrated, or even desperate.

Here are 3 ways of building Javet.

All of them share the same build environment in the next section.
