Injects given string to file between two delimiters.

NOTE 1: all data between the given delimiter is replaced by the new data. Use at your own risk.

NOTE 2: this module is not as efficient as it could be. It currently loads the entire file in memory. If you need to do this frequently, you should consider a streaming based approach.


npm install finjector

Example 1

var finjector       = require('finjector'),
    injectFile      = __dirname + '/bootstrap.js',
    data            = 'this is an example entry to be injected between the delimiters', 
    startDelimiter  = '/* routines-start */\n',
    endDelimiter    = '\n/* routines-end */';

finjector.inject(injectFile, data, startDelimiter, endDelimiter, function(err) {
    if (err) throw new Error('Failed to inject to file: ' + err);
    console.log('successfully injected data to file between delimiters');
