Usage examples: filtering

const mockfs = require('mock-fs'); const walk = require('@bem/sdk.walk'); const react = require('@bem/sdk.naming.presets/react'); const util = require("util"); const toArray = require('stream-to-array'); const entities = []; mockfs({ 'src/components': { 'btn': { 'btn.js': 'alert(1)', 'btn.css': '.btn { color: red }', 'btn.examples': { 'all.bemjson.js': '({ block: "btn" })' }, 'btn@desktop.js': 'alert(2)', 'btn@touch.js': 'alert(3)', 'text/btn-text.js': '// oh really\n', }, }, 'node_modules/react-components': { 'input': { 'input.ts': 'alert(4)', 'input.styl': '.btn { color: red }', 'input@desktop.ts': 'alert(5)', 'input@touch.ts': 'alert(6)', } } }); await toArray(walk( ['src/components', 'node_modules/react-components'], { defaults: { naming: react } } )).then(files => files.filter(file => { // Getting the block name for a found file. const block = file.entity.block; // Adding information about the found file. if (block == 'input') { entities.push(file); } })); console.log(util.inspect(entities, { depth: null }));
