v10.0.0

[10.0.0] - 2020-11-08

Breaking

• Specifiying both the --filter option and argument filters will now throw an error. Use one or the other. Previously the arguments would override the --filter option, which made for a confusing result when accidentally not quoting the option in the shell. This change is only breaking for those who are relying on the incorrect behavior of argument filters overriding --filter.

See: #759

v9.2.4...v10.0.0

v9.0.0

[9.0.0] - 2020-09-10

Breaking

• Versions marked as deprecated in npm are now ignored by default. If the latest version is deprecated, the highest non-deprecated version will be suggested. Use --deprecated to include deprecated versions (old behavior).

v8.1.1...v9.0.0

v8.0.0

Breaking

• --semverLevel major is now --target minor. --semverLevel minor is now --target patch. This change was made to provide more intuitive semantics for --semverLevel (now --target). Most people assumed it meant the inclusive upper bound, so now it reflects that. a2111f4c2
• Programmatic usage: run now defaults to silent: true instead of loglevel: 'silent, unless loglevel is explicitly specified. If you overrode silent or loglevel, this may affect the logging behavior. 423e024

Deprecated

Options that controlled the target version (upper bound) of upgrades have been consolidated under --target. The old options are aliased with a deprecation warning and will be removed in the next major version. No functionality has been removed.

• --greatest: Renamed to --target greatest
• --newest: Renamed to --target newest
• --semverLevel: Renamed to --target

Features

Doctor Mode

#722

Usage: ncu --doctor [-u] [options]

Iteratively installs upgrades and runs tests to identify breaking upgrades. Add -u to execute (modifies your package file, lock file, and node_modules).

To be more precise:

1. Runs npm install and npm test to ensure tests are currently passing.
2. Runs ncu -u to optimistically upgrade all dependencies.
3. If tests pass, hurray!
4. If tests fail, restores package file and lock file.
5. For each dependency, install upgrade and run tests.
6. When the breaking upgrade is found, saves partially upgraded package.json (not including the breaking upgrade) and exits.

Example:

$ ncu --doctor -u
npm install
npm run test
ncu -u
npm install
npm run test
Failing tests found:
/projects/myproject/test.js:13
  throw new Error('Test failed!')
  ^
Now let's identify the culprit, shall we?

Github URLs

Added support for GitHub URLs.

See: f0aa792a4

Example:

{
  "dependencies": {
    "chalk": "https://github.com/chalk/chalk#v2.0.0"
  }
}

npm aliases

Added support for npm aliases.

See: 0f6f35c

Example:

{
  "dependencies": {
    "request": "npm:[email protected]"
  }
}

Owner Changed

#621

Usage: ncu --ownerChanged

Check if the npm user that published the package has changed between current and upgraded version.

Output values:

• Owner changed: *owner changed*
• Owner has not changed: no output
• Owner information not available: *unknown*

Example:

$ ncu --ownerChanged
Checking /tmp/package.json
[====================] 1/1 100%

 mocha  ^7.1.0  →  ^8.1.3  *owner changed*

Run ncu -u to upgrade package.json

Commits

v7.1.1...v8.0.0

v7.0.0

Breaking

• Removed bower support (4e4b47f)

Patch

• Fix use of "<" with single digit versions (f04d00e)

Other

• Change eslint configuration
• Update dependencies
• Replace cint methods with native methods
• Add CI via GitHub Actions workflow

v6.0.0

Breaking

• --semverLevel now supports version ranges. This is a breaking change since version ranges are no longer ignored by --semverLevel, which may result in some dependencies having new suggested updates.

If you are not using --semverLevel, NO CHANGE! 😅

v5.0.0

Breaking*

node >= 8
node >= 10.17

Bump minimum node version to v10.17.0 due to move-file #651

*If ncu was working for you on v4.x, then v5.0.0 will still work. Just doing a major version bump since ncu's officially supported node version is changing. v4 should be patched to be compatible with node v8, but I'll hold off unless someone requests it.

v4.1.0

Feature

• Added --concurrency to set the maximum number of concurrent HTTP requests to the npm registry (default: 8).

Fix

• Pass --timeout correctly to pacote so that process is properly terminated when timeout is exceeded.

v4.0.0

ncu v3 excluded prerelease versions (-alpha, -beta, etc) from the remote by default, as publishing prerelease versions to latest is unconventional and not recommended. Prereleases versions can be included by specifying --pre (and is implied in options --greatest and --newest).

However, when you are already specifying a prerelease version in your package.json dependencies, then clearly you want ncu to find newer prerelease versions. This is now default in v4, albeit with the conservative approach of sticking to the latest tag.

Migration

No effect for most users.

If a prerelease version is published on the latest tag, and you specify a prerelease version in your package.json, ncu will now suggest upgrades for it.

If a prerelease version is published on a different tag, there is no change from ncu v3; you will still need --pre, --greatest, or --newest to get prerelease upgrades.

v3.2.0

Added --engines-node option to include only packages that satisfy engines.node as specified in the package file.

See unit tests for detailed behavior.

v3

Breaking changes

node < 8 deprecated

The required node version has been updated to allow the use of newer Javascript features and reduce maintenance efforts for old versions.

System npm used

In ncu v2, an internally packaged npm was used for version lookups. When this became out-of-date and differed considerably from the system npm problems would occur. In ncu v3, the system-installed npm will be used for all lookups. This comes with the maintenance cost of needing to upgrade ncu whenever the output format of npm changes.

Installed modules ignored

In ncu v2, out-of-date dependencies in package.json that were installed up-to-date (e.g. ^1.0.0 specified and 1.0.1 installed) were ignored by ncu. Installed modules are now completely ignored and ncu only consider your package.json. This change was made to better match users’ expectations.

Existing version ranges that satisfy latest are ignored (-a by default)

In ncu v2, if you had ^1.0.0 in your package.json, a newly released 1.0.1 would be ignored by ncu. The logic was that ^1.0.0 is a range that includes 1.0.1, so you don’t really need to change the version specified in your package.json, you just need to run npm update. While logical, that turned out to be quite confusing to users. In ncu v3, the package.json will always be upgraded if there is a newer version (same as -a in v2). The old default behavior is available via the --minimal option.

Prerelease versions ignored

In ncu v2, any version published to the latest tag was assumed to be a stable release version. In practice, occasional package authors would accidentally or unconventionally publish -alpha, -beta, and -rc versions to the latest tag. While I still consider this a bad practice, ncu v3 now ignores these prerelease versions by default to better match users’ expectations. The old behavior is available via the --pre 1 option. (When --newest or --greatest are set, --pre 1 is set by default, and can be disabled with --pre 0).

Options changed: -m, --prod, --dev, --peer

In order to only target one or more dependency sections, ncu now uses the --dep option instead of separate options for each section.

--prod is now --dep prod
--dev is now --dep dev
--dev --peer is now --dep dev,peer etc

The --packageManager alias has changed from -m to -p to make room for --minimal as -m.
