Package Exports

single-line-log

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (single-line-log) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

single-line-log

Node.js module that keeps writing to the same line in the console (or a stream). Very useful when you write progress bars, or a status message during longer operations. Supports multilines.

Installation

npm install single-line-log

Usage

var log = require('single-line-log').stdout;
// or pass any stream:
// var log = require('single-line-log')(process.stdout);

var read = 0;
var size = fs.statSync('super-large-file').size;

var rs = fs.createReadStream('super-large-file');
rs.on('data', function(data) {
    read += data.length;
    var percentage = Math.floor(100*read/size);

    // Keep writing to the same two lines in the console
    log('Writing to super large file\n[' + percentage + '%]', read, 'bytes read');
});

.clear()

Clears the log (i.e., writes a newline).

var log = require('single-line-log').stdout;

log('Line 1');
log.clear();
log('Line 2');

.stdout

Outputs to process.stdout.

.stderr

Outputs to process.stderr.
