yang-parser

library0.2.1jsnpmunverified

A parser for the YANG data modeling language (RFC 7950) written in CoffeeScript using the Comparse functional parsing library. Current stable version 0.2.1 performs lexical analysis and returns a tree of YANG statements without syntactic or semantic validation. The package has not been updated since 2017 and is considered stable but unmaintained. It is primarily for Node.js usage and depends on Comparse.

Code

Verified usage

Verified import paths — ran on the pinned version, not inferred.

parse

✓ import { parse } from 'yang-parser'

✗ const yangParser = require('yang-parser');

The package has no default export; use named import.

parse

✓ const { parse } = require('yang-parser')

CommonJS require with destructuring is also valid.

parse

✓ import { parse } from 'yang-parser'

✗ import parse from 'yang-parser'

Default import is incorrect; the module exports an object with parse.

Parses a YANG module string and logs the resulting JSON tree.

import { parse } from 'yang-parser'; const yangSource = ` module example { namespace "urn:example:system"; prefix sys; organization "Example Inc."; contact "admin@example.com"; description "Example module"; revision 2024-01-01 { description "Initial revision"; } container system { leaf hostname { type string; } } }`; try { const result = parse(yangSource); console.log(JSON.stringify(result, null, 2)); } catch (err) { console.error('Parse error:', err.message); }

Debug

Known issues

deprecatedPackage is unmaintained since 2017; may not support newer YANG RFCs or grammar changes.

fix

Consider migrating to a maintained YANG parser such as yang-parser-js or pyang.

affects: >=0.0.0

gotchaParser only performs lexical analysis; no syntactic or semantic validation. Invalid YANG may parse without error.

fix

Validate output with a separate tool like pyang.

affects: >=0.0.0

breakingDepends on Comparse library which may have breaking changes in newer versions; not pinned.

fix

Install with legacy peer deps if using npm v7+.

affects: >=0.2.0

Errors

Common errors & fixes

Cannot find module 'yang-parser'

Package not installed or module resolution fails.

fix

Run 'npm install yang-parser' in your project directory.

TypeError: yangParser is not a function

Using default import when named import is required.
