shrink-yarn-lock v1.2.0

shrink-yarn-lock

In case you are managing a lot of dependencies, sometimes yarn adds a lot of separate entries to lock file even if the same package could be reused for them.

shrink-yarn-lock allows you to optimise yarn.lock file merging together dependencies if they satisfy the same currently installed package version. This will help to save some time on downloading packages and unpacking them, along with space on file system.

Example

ajv@^6.1.0:
  version "6.5.1"
  resolved "https://registry.yarnpkg.com/ajv/-/ajv-6.5.1.tgz#88ebc1263c7133937d108b80c5572e64e1d9322d"
  integrity sha1-iOvBJjxxM5N9EIuAxVcuZOHZMi0=
  dependencies:
    fast-deep-equal "^2.0.1"
    fast-json-stable-stringify "^2.0.0"
    json-schema-traverse "^0.4.1"
    uri-js "^4.2.1"

ajv@^6.5.5:
  version "6.10.0"
  resolved "https://registry.yarnpkg.com/ajv/-/ajv-6.10.0.tgz#90d0d54439da587cd7e843bfb7045f50bd22bdf1"
  integrity sha1-kNDVRDnaWHzX6EO/twRfUL0ivfE=
  dependencies:
    fast-deep-equal "^2.0.1"
    fast-json-stable-stringify "^2.0.0"
    json-schema-traverse "^0.4.1"
    uri-js "^4.2.2"

ajv@^6.6.1:
  version "6.7.0"
  resolved "https://registry.yarnpkg.com/ajv/-/ajv-6.7.0.tgz#e3ce7bb372d6577bb1839f1dfdfcbf5ad2948d96"
  integrity sha1-4857s3LWV3uxg58d/fy/WtKUjZY=
  dependencies:
    fast-deep-equal "^2.0.1"
    fast-json-stable-stringify "^2.0.0"
    json-schema-traverse "^0.4.1"
    uri-js "^4.2.2"

becomes just

ajv@^6.1.0, ajv@^6.5.5, ajv@^6.6.1:
  version "6.10.0"
  resolved "https://registry.yarnpkg.com/ajv/-/ajv-6.10.0.tgz#90d0d54439da587cd7e843bfb7045f50bd22bdf1"
  integrity sha1-kNDVRDnaWHzX6EO/twRfUL0ivfE=
  dependencies:
    fast-deep-equal "^2.0.1"
    fast-json-stable-stringify "^2.0.0"
    json-schema-traverse "^0.4.1"
    uri-js "^4.2.2"

Usage

npm i -g shrink-yarn-lock
shrink-yarn-lock <optional: path to yarn.lock>

Then run yarn to make sure your lock file is valid and to remove obsolete dependencies which might have been referenced by older versions of merged packages.
