    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.
