depend

A tool for analysing, visualizing and syncing version numbers in a monorepo.

This tool parses all package.json files described in your lerna.json or that match a given glob-expression. All packages found are assumed to be part of one monorepo.

Linting

Based on the parsed packages, linting rules are computed. Based on those rules, hints are computed and can be displayed using --hint and applied with --fix. Strategies add additional rules for ensuring packages install the same external dependencies. By default, only rules are computed that ensure that every package installs the latest version of each package found in the monorepo.

Analysis

--list prints all package versions found in the monorepo. Based on the used rules, packages will be rendered in different colours:

  • Green => nothing to do.
  • Yellow => rules available to resolve the conflict.
  • Red => no rule available to resolve this conflict.

If no rules are available, set a strategy or fix the issue by using --pick.

Usage

depend --lerna "{path/to/lerna/project}" [...options]
depend --expr "{glob}" [...options]

Options

--lerna, -l "{path}"

Evaluate all package.json files defined in the packages field found <path>/lerna.json file.

--expr, -e "{glob}"

Defines the glob expression that will be used to search the filesystem for package.json files.

--fix

Fixes the packages according to the computed versions.

--graph, -g "{filter}"

Prints a graphviz compatible output that can be converted to an image.

--list

prints all package versions found in the monorepo.

'--showRules'

prints all computed rules.

Examples

Consider following repo:

packages/foo/package.json:

{
  "name": "foo",
  "version": "0.0.1",
  "dependencies": {
    "react": "16.10.0",
    "bar": "0.0.1"
  }
}

packages/bar/package.json:

{
  "name": "bar",
  "version": "0.0.2",
  "dependencies": {
    "react": "16.9.0",
    "glob": "6.2.1"
  }
}

depend -l . -g outputs all dependencies in .dot format:

  digraph {
    "foo@0.0.1" -> "react@16.10.0";
    "foo@0.0.1" -> "bar@0.0.1";
    "bar@0.0.2" -> "react@16.9.0";
    "bar@0.0.2" -> "glob@6.2.1";
  }

depend -l . -g "*=>react" will only outputs the subset that has reacte as a dependency:

digraph {
  "foo@0.0.1" -> "react@16.10.0";
  "bar@0.0.2" -> "react@16.9.0";
}

depend -l . -g "foo=>*" will only outputs the subset that has react as a dependency:

digraph {
  "foo@0.0.1" -> "react@16.10.0";
  "foo@0.0.1" -> "bar@0.0.1";
}

Rendering Svgs

Depend itself does not have any rendering capabilities but --graph output can be directly piped into a graphviz renderer. fdp and circo can be obtained by installing the graphviz package.

depend -l . -g "@times-components/*=>dextrose@" | fdp -Tsvg -o dextrose.svg

dextrose

depend -l . -g "*/ad@ => *" | circo -Tgif -o ad.gif

ad

--pick, -p {package}@{version}

Adds {package}@{version} to the set of rules. Use this in conjunction with --hint to verify the expected behaviour and use --fix to apply the changes.

depend -l . --pick react@16.10.0 --hint would set all react dependencies to 16.10.0

Filter

The filter allows you to restrict the nodes that will be part of the graph.

The graph is described as a set of relationship of the shape package@version => dependency@version. A Node is included in the graph if the supplied pattern matches the relationship. Currently only supported placeholder symbol is "*".

Examples

=>react@16.9.*

everything that installs react ver16.9.*

=>jest

everything that installs jest

@times-components/*=>*, @times-components

all the dependencies of all times-components packages

*=>* , , *

everything

--bail

exit with code 1 if packages don't install the expected versions.

strategies --strategy, -s

Strategies compute additional rules how to resolve version conflicts of external (dev)dependencies within the monorepo.

Dependencies that are also packages of the monorepo, are always (suggested to be) set to the latest version found in the monorepo irrespective of the chosen strategy.

conservative

pick the oldest used version

progressive

pick the newest used version

majority

use the version that is used by the majority of packages in your repo

majorityConservative

as majority but on a tie pick the older version

majorityProgressive

as majority but on a tie pick the newer version

Limitations

Strategies progressive and conservative don't support version ranges.
