What is lock-verify?
The lock-verify npm package is used to verify the integrity of package-lock.json files. It ensures that the dependencies listed in the package-lock.json file are consistent with the actual installed node_modules directory. This helps in maintaining the integrity and consistency of the project dependencies.
What are lock-verify's main functionalities?
Verify package-lock.json
This feature verifies the integrity of the package-lock.json file against the node_modules directory. If the verification is successful, it logs a success message; otherwise, it logs the errors.
const lockVerify = require('lock-verify');
lockVerify().then(result => {
if (result.status === 'success') {
console.log('package-lock.json is valid');
} else {
console.error('package-lock.json is invalid');
console.error(result.errors);
}
}).catch(err => {
console.error('An error occurred:', err);
});
Other packages similar to lock-verify
npm-audit
npm-audit is a built-in npm command that performs a security audit of the project's dependencies. While it focuses on security vulnerabilities rather than integrity verification, it provides a comprehensive report on potential security issues in the dependencies.
yarn
Yarn is an alternative package manager to npm that also provides a lock file (yarn.lock) to ensure consistent dependency installations. Yarn has a built-in command `yarn check` that verifies the integrity of the installed packages against the yarn.lock file, similar to what lock-verify does for npm.
npm-check
npm-check is a tool that checks for outdated, incorrect, and unused dependencies in a project. While it does not specifically verify the package-lock.json file, it helps in maintaining the overall health of the project's dependencies.
Note: pending imminent deprecation
This module will be deprecated once npm v7 is released. Please do not rely
on it more than absolutely necessary (ie, only if you are depending on
it for use with npm v6 internal dependencies).
lock-verify
Report if your package.json is out of sync with your package-lock.json.
USAGE
const lockVerify = require('lock-verify')
lockVerify(moduleDir).then(result => {
result.warnings.forEach(w => console.error('Warning:', w))
if (!result.status) {
result.errors.forEach(e => console.error(e))
process.exit(1)
}
})
As a library it's a function that takes the path to a module and returns a
promise that resolves to an object with .status
, .warnings
and .errors
properties. The first will be true if everything was ok (though warnings
may exist). If there's no package.json
or no lockfile in moduleDir
or they're
unreadable then the promise will be rejected.
