mysqldump-search-replace

mysqldump-search-replace-node

A node.js module that replaces a string in a MySQL dump and fixes serialized data. This is helpful when migrating a WordPress database from one host to another and the urls change.

Installation

Install the module via npm install:

$ npm install --save mysqldump-search-replace

Usage

The module consists of a simple function that takes a dump string, a search string and a replace string. It then replaces all occurrences of the search string by the replace string. Afterwards, serialized data length values in the dump are fixed.

var fs = require('fs');
var mysqldumpSearchReplace = require('mysqldump-search-replace');
 
var content = fs.readFileSync('dump.sql', 'utf-8');
 
var newContent = mysqldumpSearchReplace(
  content,
  'http://local-project.here',
  'http://live-project.com'
);

Caution: Only string lengths are fixed currently. Array values might also become inconsistent, but which shouldn't be the case in the WordPress scenario.
