Run commands in all projects in the current directory. Handle monorepos with ease.

Features

• No configuration necessary. Run puby anywhere. It won't complain.
• Execute pub get in seconds rather than minutes with puby link
• Reclaim disk space with puby clean
• Supports all project-level pub commands
• Execute any command in all projects with puby exec
• Determines the project engine (dart, flutter, fvm) automatically
• Convenience shortcuts for common dart/flutter commands
• Combined exit code for use in CI
• Per-project command exclusions

Command	Equivalent
puby [args]	[engine] pub [args]
puby link	Warm the pub cache and run [engine] pub get --offline
puby gen	dart run build_runner build --delete-conflicting-outputs
puby run	dart run
puby test	[engine] test
puby clean	flutter clean
puby mup	[engine] pub upgrade --major-versions
puby reset	puby clean && puby get
puby relink	puby clean && puby link
puby exec [command]	command

For projects configured with FVM, fvm flutter and fvm dart are used. FVM support can be disabled with the --no-fvm option.

Use as an executable

Installation

$ dart pub global activate puby

Usage

$ puby get
$ puby upgrade --major-versions
...

Notes on puby link

This command is based on flutter update-packages. All of the dependencies required by all of the projects in the current directory are cataloged and cached if necessary, then pub get --offline can safely run in all the projects in parallel.

This command no longer requires existing pubspec.lock files to function and instead uses the same version resolution strategy from the pub command to catalog dependencies.

The puby link command can run many times faster than puby get, so it is very useful for large mono-repos.

Benchmarks in the flutter/packages repo:

Command	Duration
puby get	9:01.97
melos bootstrap	47.810
puby link	25.881

Benchmark setup:

• M3 MacBook Pro
• Gigabit internet connection
• Run puby clean && dart pub cache clean before each run
• melos bootstrap is run with a custom branch of flutter/packages with the required setup

Notes on puby gen and puby run

Commands that map to dart run [package] will not run in projects that do not depend on the required package. For example, puby gen will skip projects that do not depend on build_runner. Transitive dependencies are included in this check, however a pub get must be run in the project at least once for the check to work.

Notes on puby exec

Paths relative to the directory you are running puby in will not work. For example:

• puby exec ./foo.sh will not work
• puby exec $PWD/foo.sh will work

Configuration

Create a puby.yaml file in the root of the project you want to configure

Exclusions

Add command exclusions to prevent them from running in a project

exclude:
  - test
  - pub run build_runner

Exclusions match from the start of a command, and the entire exclusion string must be present. Here are some examples:

Exclusion	Example command excluded
test	[engine] test --coverage
pub run build_runner	[engine] pub run build_runner build
