bun pm

Package manager utilities

The bun pm command group provides a set of utilities for working with Bun's package manager.

pack

To create a tarball of the current workspace:

bun pm pack

This command creates a .tgz file containing all files that would be published to npm, following the same rules as npm pack.

Examples

Basic usage:

bun pm pack
# Creates my-package-1.0.0.tgz in current directory

Quiet mode for scripting:

TARBALL=$(bun pm pack --quiet)
echo "Created: $TARBALL"

Created: my-package-1.0.0.tgz

Custom destination:

bun pm pack --destination ./dist
# Saves tarball in ./dist/ directory

Options

• --dry-run: Perform all tasks except writing the tarball to disk. Shows what would be included.
• --destination <dir>: Specify the directory where the tarball will be saved.
• --filename <name>: Specify an exact file name for the tarball to be saved at.
• --ignore-scripts: Skip running pre/postpack and prepare scripts.
• --gzip-level <0-9>: Set a custom compression level for gzip, ranging from 0 to 9 (default is 9).
• --quiet: Only output the tarball filename, suppressing verbose output. Ideal for scripts and automation.

Note: --filename and --destination cannot be used at the same time.

Output Modes

Default output:

bun pm pack

bun pack v1.2.19

packed 131B package.json
packed 40B index.js

my-package-1.0.0.tgz

Total files: 2
Shasum: f2451d6eb1e818f500a791d9aace80b394258a90
Unpacked size: 171B
Packed size: 249B

Quiet output:

bun pm pack --quiet

my-package-1.0.0.tgz

The --quiet flag is particularly useful for automation workflows where you need to capture the generated tarball filename for further processing.

bin

To print the path to the bin directory for the local project:

bun pm bin

/path/to/current/project/node_modules/.bin

To print the path to the global bin directory:

bun pm bin -g

<$HOME>/.bun/bin

ls

To print a list of installed dependencies in the current project and their resolved versions, excluding their dependencies.

bun pm ls
# or
bun list

/path/to/project node_modules (135)
├── [email protected]
├── [email protected]
├── [email protected]
├── [email protected]
└── [email protected]

To print all installed dependencies, including nth-order dependencies.

bun pm ls --all
# or
bun list --all

/path/to/project node_modules (135)

hash

To generate and print the hash of the current lockfile:

bun pm hash

To print the string used to hash the lockfile:

bun pm hash-string

To print the hash stored in the current lockfile:

bun pm hash-print

cache

To print the path to Bun's global module cache:

bun pm cache

To clear Bun's global module cache:

bun pm cache rm

migrate

To migrate another package manager's lockfile without installing anything:

bun pm migrate

untrusted

To print current untrusted dependencies with scripts:

bun pm untrusted

./node_modules/@biomejs/biome @1.8.3
 » [postinstall]: node scripts/postinstall.js

These dependencies had their lifecycle scripts blocked during install.

trust

To run scripts for untrusted dependencies and add to trustedDependencies:

bun pm trust <names>

Options for the trust command:

• --all: Trust all untrusted dependencies.

default-trusted

To print the default trusted dependencies list:

bun pm default-trusted

see the current list on GitHub here

version

To display current package version and help:

bun pm version

bun pm version v1.3.3 (ca7428e9)
Current package version: v1.0.0

Increment:
  patch      1.0.0 → 1.0.1
  minor      1.0.0 → 1.1.0
  major      1.0.0 → 2.0.0
  prerelease 1.0.0 → 1.0.1-0
  prepatch   1.0.0 → 1.0.1-0
  preminor   1.0.0 → 1.1.0-0
  premajor   1.0.0 → 2.0.0-0
  from-git   Use version from latest git tag
  1.2.3      Set specific version

Options:
  --no-git-tag-version Skip git operations
  --allow-same-version Prevents throwing error if version is the same
  --message=<val>, -m  Custom commit message, use %s for version substitution
  --preid=<val>        Prerelease identifier (i.e beta → 1.0.1-beta.0)
  --force, -f          Bypass dirty git history check

Examples:
  bun pm version patch
  bun pm version 1.2.3 --no-git-tag-version
  bun pm version prerelease --preid beta --message "Release beta: %s"

To bump the version in package.json:

bun pm version patch

v1.0.1

Supports patch, minor, major, premajor, preminor, prepatch, prerelease, from-git, or specific versions like 1.2.3. By default creates git commit and tag unless --no-git-tag-version was used to skip.

pkg

Manage package.json data with get, set, delete, and fix operations.

All commands support dot and bracket notation:

scripts.build              # dot notation
contributors[0]            # array access
workspaces.0               # dot with numeric index
scripts[test:watch]        # bracket for special chars

Examples:

# get
bun pm pkg get name                               # single property
bun pm pkg get name version                       # multiple properties
bun pm pkg get                                    # entire package.json
bun pm pkg get scripts.build                      # nested property

# set
bun pm pkg set name="my-package"                  # simple property
bun pm pkg set scripts.test="jest" version=2.0.0  # multiple properties
bun pm pkg set {"private":"true"} --json          # JSON values with --json flag

# delete
bun pm pkg delete description                     # single property
bun pm pkg delete scripts.test contributors[0]    # multiple/nested

# fix
bun pm pkg fix                                    # auto-fix common issues
