Installation

# use npm
npm install progress-estimator

# use yarn
yarn add progress-estimator

Usage example

const createLogger = require('progress-estimator');
const { join } = require('path');

// All configuration keys are optional, but it's recommended to specify a storage location.
// Learn more about configuration options below.
const logger = createLogger({
  storagePath: join(__dirname, '.progress-estimator'),
});

async function run() {
  await logger(promiseOne, "This is a promise");
  await logger(
    promiseTwo,
    "This is another promise. I think it will take about 1 second",
    {
      estimate: 1000
    }
  );
}

API

createLogger(optionalConfiguration)

This method is the default package export. It creates and configures a logger function (documented below). The following configuration options are supported. (They apply only to the logger instance that's returned.)

name type Description
logFunction Function Custom logging function. Defaults to log-update. Must define .done() and .clear() methods.
spinner object Which spinner from the cli-spinners package to use. Defaults to dots.
storagePath string Where to record durations between runs. Defaults to os.tmpdir().
theme object Custom chalk theme. Look to the default theme for a list of required keys.

logger(promise, labelString, options)

This method logs a progress bar and estimated duration for a promise. It requires at least two parameters– a Promise and a label (e.g. "Running tests"). The label is SHA1 hashed in order to uniquely identify the promise.

An optional third parameter can be provided as well with the following keys:

name type Description
estimate Number Estimated duration of promise. (This value is used initially, until a history of actual durations have been recorded.)
id String Uniquely identifies the promise. This value is needed if the label string is not guaranteed to be unique.
