ipfs-utils

js-ipfs-utils

This package serves as a central repository for shared logic and dependencies for all IPFS packages, using ipfs-utils helps to easily re-use small scoped blocks of logic across all the js core interface implementations and also as a dependency proxy (think aegir for domain logic dependencies).

ipfs-utils aims to provide single function default export per file (with a few exceptions) scoped in 3 general categories:

• General use
• Data structs wrangling (arrays, objects, streams, etc)
• IPFS core subsystems

General use and Data structs wrangling should try to be just re-exports of community packages.

The IPFS ecosystem has lots of repos with it comes several problems like:

• Domain logic dedupe - all interface-core implementations shared a lot of logic like validation, streams handling, etc.
• Dependencies management - it's really easy with so many repos for dependencies to go out of control, they become outdated, different repos use different modules to do the same thing (like merging defaults options), browser bundles ends up with multiple versions of the same package, bumping versions is cumbersome to do because we need to go through several repos, etc.

These problems are the motivation for this package, having shared logic in this package avoids creating cyclic dependencies, centralizes common use modules/functions (exactly like aegir does for the tooling), semantic versioning for 3rd party dependencies is handled in one single place (a good example is going from streams 2 to 3) and maintainers should only care about having ipfs-utils updated.
