Mongo URI Total Translator

(aka MUTT)

Are you sick of translating between the Mongo URIs your applications use and the actual commands you need to send to the mongo command line tool?

Me too! This is a little utility that does the translation for you.

Made by Kevin Brown, supported by Thinkmill. Thank you for making this project possible!

Installation

yarn global add mongo-uri-total-translator

or

npm install -g mongo-uri-total-translator

Once you've got it installed, you can do this:

$ mutt "mongodb://admin:[email protected]:27017,test-live-shard-00-01-pvesn.mongodb.net:27017,test-live-shard-00-02-pvesn.mongodb.net:27017/database?ssl=true&replicaSet=Test-Live-shard-0&authSource=admin"

Which results in:

Running command:
mongo "mongodb://test-live-shard-00-00-pvesn.mongodb.net:27017,test-live-shard-00-01-pvesn.mongodb.net:27017,test-live-shard-00-02-pvesn.mongodb.net:27017/database?replicaSet=Test-Live-shard-0" --authenticationDatabase "admin" --ssl --username "admin" --password "password"

MongoDB shell version v3.4.1
connecting to: mongodb://test-live-shard-00-00-pvesn.mongodb.net:27017,test-live-shard-00-01-pvesn.mongodb.net:27017,test-live-shard-00-02-pvesn.mongodb.net:27017/database?replicaSet=Test-Live-shard-0
...etc...

Also, you can pass additional arguments, which will just get quoted and sent straight through to mongo:

$ mutt "mongodb://test" --eval "printjson(db.getCollectionNames())"

Running command:
mongo "mongodb://test:27017/test" "--eval" "printjson(db.getCollectionNames())"

MongoDB shell version v3.4.1
connecting to: mongodb://test:27017/test

...etc...

Why do I need this?

I find it really odd that the mongo command line tool can't take a connection URI in the same format that the drivers do. Let's say I want to test a connection from a server, and I have the URI from a configuration file / environment variables / wherever. I have a few options:

1. Play around with my app, trying to see what's going on.
2. Build a little program that uses the same mongo URI to try to connect and play with that.
3. Mentally translate between the URI options and the command line options and construct a mongo command to replicate the problem.

I find the last option to be the best in general, except Mongo seems to intentionally make it difficult to translate between these worlds with odd differences like authSource vs --authenticationDatabase etc.

After I had spent quite a bit of time debugging my own mental translation process between these two worlds, I realised others would be suffering from the same problem and that we should just automate this process.

What's on your roadmap?

This tool should be able to parse any valid mongo URI and create a corresponding mongo command, passing in any relevant options that it can glean from the URI.

It's in a very early state at the moment, and serves my own needs, but I want it to be more useful for everyone's needs. If you find something that should work that doesn't, please create an issue or a PR so we can fix it!

It's not working on my URI!
