inspector-api/index.js

A simple node module to access V8 inspector + some tools to export and read the data.

'use strict'

const inspector = require('inspector')
const Profiler = require('./src/profiler')
const Heap = require('./src/heap')

    constructor (config = {}) {

        let client = null
        if (!config.storage) config.storage = { type: 'raw' }
        if (config.storage.type === 's3') {
            const { S3Client } = require('@aws-sdk/client-s3')
            client = new S3Client(config.aws)
        }

        const session = new inspector.Session()
        session.connect()

        this.session = session

        this.profiler = new Profiler(this.session, config, client)
        this.heap = new Heap(this.session, config, client)

        this.session.disconnect()
        this.session = null

}
