The Julia ecosystem contains over 12,000 packages that are registered in the General registry, which means that finding the right package can be a challenge. Usually, searching with a package name with a .jl extension on a search engine helps find the right page quickly. For example, to search for the Julia dataframes package, search for dataframes.jl.
There are services that can help navigate the package ecosystem:
JuliaHub — a JuliaHub service that includes search of all registered open source package documentation, code search, and navigation by tags/keywords.
Julia Packages — browse Julia packages, filter by categories, and sort them by popularity, creation date or date of last update. Also supports browsing package developers.
Julia Package Comparisons - a website to help Julia users discover and choose between packages.
Julia has an official package manager along with its own infrastructure to build binaries and libraries:
Pkg.jl is the Julia package manager. It has extensive documentation for managing packages and developing them as well.
Julia Package Download Statistics - Package download statistics based on the announcement.
BinaryBuilder - Build native binaries with over 45 well maintained toolchains for major platforms. Refer to the BinaryBuilder.jl documentation for details.
