Hi everyone,

i was wondering if puppeteer is really necessary. I forked this repo and replaced puppeteer with fetch. It's seems works very well and the performance are better:

Fixes #121
Closes #138 #139 #145

Benchmark

Code

const run = async () => {
    const iterations = 10
    const responsesTime = []

    for (let index = 0; index < iterations; index++) {
        const start = new Date()
        await investing('1')
        responsesTime.push(new Date() - start)
        console.log(`run ${index + 1}: ${responsesTime[index]}ms`)
    }
    const avg = responsesTime.reduce((acc, responseTime) => acc + responseTime, 0) / responsesTime.length
    console.log(`avg: ${avg}ms`)
}
