Advanced tools
Package description
The validate-npm-package-license package is used to validate and parse license identifiers based on the SPDX license list. It helps ensure that package licenses are valid and SPDX-compliant, which is important for legal compliance and software distribution.
License Validation
This feature allows you to validate a string to check if it's a valid SPDX license expression. The code sample demonstrates how to validate the 'MIT' license identifier.
"use strict";\nconst validate = require('validate-npm-package-license');\nconst result = validate('MIT');\nconsole.log(result);License Parsing
This feature enables parsing of complex SPDX license expressions, such as dual licenses. The code sample shows how to parse and validate a compound license expression that includes both 'MIT' and 'Apache-2.0' licenses.
"use strict";\nconst validate = require('validate-npm-package-license');\nconst result = validate('(MIT OR Apache-2.0)');\nconsole.log(result);The spdx-correct package is designed to help correct invalid SPDX license IDs to their nearest valid identifiers. It is similar to validate-npm-package-license in that it deals with SPDX licenses, but it focuses more on correcting typos and common mistakes rather than validation.
This package provides functionality to parse SPDX license expressions, similar to one of the features of validate-npm-package-license. However, spdx-expression-parse focuses solely on parsing and does not include validation against the SPDX license list.
