bootsnap
A Ruby library that speeds up application boot time by caching expensive computations like path lookups and code compilation.
What is bootsnap?
Bootsnap is a Ruby gem that optimizes application boot time by caching expensive computations like filesystem path lookups and code compilation. It plugs into Ruby's `require` and `load` mechanisms to eliminate redundant work, reducing boot times by up to 75% for large Rails applications.
Ruby and Rails developers working on large monolithic applications with slow boot times, particularly in development and production environments where rapid restart is valuable.
Developers choose Bootsnap because it provides significant boot time reductions with minimal configuration, works alongside existing tools like Spring, and is production-safe with no application code changes required.
