agg-compiler

1.3.2 verified Fri May 01 auth: no javascript deprecated

The agg-compiler package (version 1.3.2) is a specialized tool for compiling aggregation pipelines, typically used with database query frameworks like MongoDB or similar. It lacks an official description or README, indicating limited community adoption or poor documentation. The package appears to be niche, with no clear release cadence or differentiators from other query builders. As of the latest version, users rely solely on the npm metadata, which suggests it may be experimental or abandoned.

const aggCompiler = require('agg-compiler');
const pipeline = [{ $match: { status: 'active' } }, { $group: { _id: '$category', count: { $sum: 1 } } }];
const compiled = aggCompiler.compile(pipeline);
console.log(compiled);
// Output: compiled query string or pipeline
console.log('Check for deprecation warnings.');
