A CLI to lint a lockfile for security policies
A CLI tool to lint a lockfile for security policies
npm install --save lockfile-lint
lockfile-lint can be installed per a project scope, or globally and exposes a
lockfile-lint executable that should be practiced during builds, CIs, and general static code analysis procedures to ensure that lockfiles are kept up to date with pre-defined security and usage policies.
lockfile-lint --type <yarn|npm> --path <path-to-lockfile> --validate-https --allowed-hosts <host-to-match> --allowed-urls <urls-to-match>
An example of running the linter with debug output for a yarn lockfile and asserting that all resources are using the official npm registry as source for packages:
DEBUG=* lockfile-lint --path yarn.lock --type yarn --allowed-hosts npm
Example 2: specify hostnames and enforce the use of HTTPS as a protocol
lockfile-lint --path yarn.lock --allowed-hosts registry.yarnpkg.com --validate-https
--type yarnis ommitted since lockfile-lint can figure it out on it's own
--allowed-hostsexplicitly set to match yarn's mirror host
Example 3: allow the lockfile to contain packages served over github and so need to specify github.com as a host as well as the
git+https: as a valid URI scheme
lockfile-lint --path yarn.lock --allowed-hosts yarn github.com --allowed-schemes "https:" "git+https:"
--allowed-hostsexplicitly set to match github.com as a host and specifies
yarnas the alias for yarn's official mirror host
--allowed-schemesis used instead of
validate-httpsand it explicitly allows both
git+https:as the HTTP Scheme for the github URL. Note that
--validate-httpsare mutually exclusive.
Example 4: allow the lockfile to contain a package which resolves to a specific URL specified by the
--allowed-urls option while all other packages must resolve to yarn as specified by
lockfile-lint --path yarn.lock --allowed-hosts yarn --allowed-urls https://github.com/lirantal/lockfile-lint#d30ce73a3e5977dede29450df1c79b09f02779b2
--allowed-hostsallows packages from yarn only
allowed-hostsand allows a specific Github URL to pass validation
CLI command options
|command line argument||description||implemented|
||path to the lockfile|
||lockfile type, options are
||validates the use of HTTPS as protocol schema for all resources in the lockfile|
||validates a list of allowed hosts to be used for all resources in the lockfile. Supported short-hands aliases are
||allowed URI schemes such as "https:", "http", "git+ssh:", or "git+https:"|
||allowed URLs (e.g.
||allow empty hostnames, or set to false if you wish for a stricter policy|
||check that all resources include a checksum||
||check that all resources include an integrity field||
Lockfile-lint uses cosmiconfig for configuration file support. This means you can configure the above options via (in order of precedence):
- A "lockfile-lint" key in your package.json file.
- A .lockfile-lintrc file, written in JSON or YAML, with optional extensions: .json/.yaml/.yml (without extension takes precedence).
- A .lockfile-lint.js or lockfilelint.config.js file that exports an object.
- A .lockfile-lint.toml file, written in TOML (the .toml extension is required).
The configuration file will be resolved starting from the current working directory, and searching up the file tree until a config file is (or isn't) found. Command-line options take precedence over any file-based configuration.
The options accepted in the configuration file are the same as the options above in camelcase (e.g. "path", "allowedHosts").
