Dependencies Update Checker

This package contains a simple script to update the dependencies of a given package file (or files).

By default it will extend the semantics of semver checking for minor version updates for tilde ranges (~x.y.z) and checking for major version updates for caret ranges (^x.y.z).

To adhere to the standard semver rules simply specify the --strict option.

When installed, the check-updates script can be invoked directly:

1$ check-updates --help
2
3Usage:
4  check-updates [--options ...] [package.json ...]
5
6Options:
7  -h, --help           Show this help.
8
9  -v, --version        Show the version and exit.
10
11  -b, --bump           Bump the version of the  package file when changes in the
12                       dependencies are found. Specifiy either "major",  "minor"
13                       or "patch" (default) to indicate which version to bump.
14
15  -s, --strict         Strictly  adhere to semver  rules for  tilde (~x.y.z) and
16                       caret (^x.y.z) dependency ranges.
17
18  -q, --quick          Consider dev/peer/optional dependency updates if and only
19                       if the main depenencies also had updates.
20
21  -d, --debug          Output debugging informations.
22
23  -x, --dry-run        Do not write package changes.
24
25      --no-errors      Exit with 0 in case  of no updates.  Normally the updater
26                       will exit with 255 in this case.
27
28      --no-workspaces  Do not process workspaces.
29
30      --no-align       Do not align workspaces versions. By default all versions
31                       will  be set to  the highest  one amongst  all workspaces
32                       after bumping.
33
34Remarks:
35  Multiple package.json files can be  specified on the command line.  In case no
36  files are specified,  the default is to process  the package.json  file in the
37  current directory.
38
39$

Alternatively it can be invoked via npx '@juit/check-updates'.

By default (unless --no-errors is specified) the exit code returned to the caller will be:

• 0: dependencies were updated and package.json was changed.
• 255: nothing was updated, no changes.
• any other: error from NodeJS.

Options

--bump (or -b)

Bump the major, minor or patch revision level if changes were detected.

By default no versions will be bumped, and when the --bump version is specified without any argument, the patch version will be bumped.

--strict (or -s)

By default, version ranges specified by ~ (tilde: match on patch version) or ^ (caret: match patch or minor versions) will be extended so that ~ will behave like ^ and match both patch and minor versions, while ^ will match any version above the one specified.

The --strict flag makes the updater work with the strict definition of ~ or ^ ranges. See here for more informations on range specifiers.

--quick (or -q)

By specifying the --quick flags, the updater will process the main dependencies first and only if any changes were detected then the other dependencies in devDependencies, peerDependencies and optionalDependencies will be processed.

--dry-run (or -x)

Only process and display changes without writing the updated package.json files.

--debug (or -d)

Dump out lots of debugging informations while updating packages.

--no-errors

By default the updater will exit with 255 if no changes were detected in the dependencies. Specifying --no-errors will make the updater exit with 0 unless a real error happened.

The 255 exit code is useful in scripts to detect whether changes were not detected. For example the following script will exit with zero if no changes were detected, will fail if an error occurred, and will perform some tasks if changes were detected:

1#!/bin/bash
2
3set -e # exit on errors
4npx '@juit/check-updates' --quick --bump || exit $(( $? == 255 ? 0 : $? ))
5# ... do stuff when changes were detected

--no-workspaces

By default the updater will recursively process workspaces defined in the various package.json files. The --no-workspaces flag disables this.

--no-align

By default, when workspaces are present, versions will be aligned to the greates versions amongst all workspaces after (if specified) bumping. When --no-align is specified,
