mongo-systemjs-tools v0.0.2

mongo-systemjs-tools

mongo-systemjs-tools

This package is a collection of utilities that can be used to manage the internal functions stored withing a database's system.js collection.

NOTE In order to use the Git integration, you'll have to use Node.js 0.12.1 or later. If not, you'll be greeted by the following when you try to run the tools:

Error: /path/to/mongo-systemjs-tools/node_modules/nodegit/build/Release/nodegit.node: undefined symbol: node_module_register
    at Module.load (module.js:356:32)
    at Function.Module._load (module.js:312:12)

Install

xxx

$ npm install --save mongo-systemjs-tools

First, you'll need to have Node.js installed. We recommend using nvm for this, as it greatly simplifies managing node versions.

git checkout https://github.com/dacgrouplabs/mongo-systemjs-tools
cd mongo-systemjs-tools
npm install

Usage

xxx

var mongoSystemjsTools = require('mongo-systemjs-tools');

mongoSystemjsTools('Rainbow');

systemjs-dump

This utility is used to dump all system.js functions to file for a specific database.

node systemjs-dump.js --url <mongouri>

systemjs-monitor

This utility can monitor a replicaset for changes, and dump those to local files.

Optionally, those files can be checked into and pushed to a remote Git repository.

Configuration

Configuration options for the utilities within this package can be found within the config.json file.

For example:

{
    "databaseUrl" : "mongodb://username:password@serverip:port/database?options",
    "outDir": "/path/to/data",
    "logLevel": "debug",
    "gitAuthor": "MongoBot",
    "gitAuthorEmail": "noreply@dacgroup.com"
}

• databaseUrl: the connection string should follow the format described in the mongo connection string docs.
• outDir: the target path where data should be written (defaults to ./out).
• logLevel: the debug level to set for the internal logger (defaults to ./info).
• gitEnabled: if set to true, commit changes to a repository and then attempt to push those changes to the origin remote (defaults to false).
• gitAuthor: the name to use as the commit author if pushing to Git (defaults to MongoBot).
• gitAuthorEmail: the email address to associate with the gitAuthor (defaults to ./info).

Git Integration

If the gitEnabled option is set, the outDir can be Git-enabled by setting up a local repo.

cd /path/to/outDir
git init

If you would like systemjs-monitor to push updates to a remote server (ex: GitHub, Bitbucket), a remote would need to be defined.

cd /path/to/outDir
git remote add origin <remote url>

TODO

• Add a lot more error handling
• Allow Git initialization of data directory (so user doesn't have to do it manually)
• Extract Git functionality so it can be used with systemjs-dump as well
• Add hooks to allow external integration (ex: mongo-linter)
• Add tests!
