👋 As you're diving into JavaScript dependencies, you might want to dive into AppSignal APM for Node.js as well. Trying to solve something that the open-source community has already solved. What else are you supposed to do? We are lucky that the JavaScript ecosystem isĪlive and thriving! We should not be reinventing the wheel every time and "This is fine" - the team lead says, as other team members nod in agreement. Makes pull requests look scary with the number of additions or deletions when package.json gets more lines over time, and package-lock.json

Even with a lot of effort on our side, packages eventually start We strive to continue to improve the npm CLI, so If you have future feedback, please leverage the npm/feedback repository discussions.Every JavaScript project starts ambitiously, trying not to use too many NPM We want to conclude by giving a big shout out to our community members who submitted changes, participated in the RFC calls, provided feedback, and were early adopters. To enforce strictly correct peer dependency resolutions at all levels, use the -strict-peer-deps flag. Since many packages in the ecosystem have come to rely on loose peer dependencies resolutions, npm 7 will print a warning and work around most peer conflicts that exist deep within the package tree, since you can’t fix those anyway. You have the option to retry with -force to bypass the conflict or -legacy-peer-deps command to ignore peer dependencies entirely (this behavior is similar to versions 4-6). npm 7 will block installations if an upstream dependency conflict is present that cannot be automatically resolved.

In previous versions of npm (4-6), peer dependencies conflicts presented a warning that versions were not compatible, but would still install dependencies without an error. Peer dependenciesĪutomatically installing peer dependencies is an exciting new feature introduced in npm 7. To avoid this, you can run npm install -no-save. Running npm install with npm 7 in a project with a v1 lockfile will replace that lockfile with the new v2 format. If a yarn.lock file is present, then npm will also keep it up-to-date with the contents of the package tree. In prior versions, the yarn.lock files were ignored, the npm CLI can now use yarn.lock as the source of package metadata and resolution guidance. The lockfile v2 unlocks the ability to do deterministic and reproducible builds to produce a package tree. One change to take note of is the new lockfile format, which is backwards compatible with npm 6 users.

You can read up on the breaking changes in the announcement blog. That said, some changes are necessary to improve the overall developer experience. If you want to install npm 6, please run npm install -global Breaking changesĭespite the massive overhaul to the internals of npm, we have worked tirelessly to ensure that there will be minimal disruptions to most workflows. Please note, npm 7 is now published as latest to the npm registry and will be the default version installed when you run npm install -global npm. Seeing significant performance improvements in various benchmarks across various examples.

Increasing code coverage by ~17% ( 94% in npm 7 vs.

Reducing dependencies by ~46% ( 67 in npm 7 and 123 in npm 6).

Increasing our development velocity/tempo to a weekly release cadence, most notably: we shipped 45 releases since August (an average of ~two a week).

In addition to new features and some breaking changes, we have made a significant impact on the performance of npm 7 as compared to npm 6 including: After much anticipation, the npm CLI version 7 is now generally available!
