Connecting to Tigris using mongosh

· 3 min read

In the previous blog post we discussed using Tigris as a scalable, cost-effective, and open source alternative to MongoDB Atlas. As a continuation of that, this blog post will demonstrate using the MongoDB Shell mongosh in a way that is transparent to the application that the data is stored in Tigris Cloud database.

Furthermore, there will be no cluster to create and no sharding to worry about.

We have also recorded a video if you prefer video content.

Prerequisites​

Create the Tigris project and generate the application key​

Login to Tigris Cloud:

tigris login

Create a Tigris project and generate the application key. The project name will be used as the MongoDB database name. The application key is used to authenticate to Tigris.

tigris create project go_mongo_quickstart
tigris create app_key default --project mongosh_quickstart

The above command will have an output similar to the following:

{
  "id": "your_client_id",
  "name": "default",
  "secret": "your_client_secret",
  "created_at": 1676857746000,
  "created_by": "google-oauth2|1111xxx",
  "project": "mongosh_quickstart"
}

Using mongosh​

Connect to Tigris​

We will use the id and secret from the output of the command above as the username and password in our URI. We will use m1k.preview.tigrisdata.cloud as the deployment to connect to.

info

Note how you did not have to create a MongoDB Atlas cluster. m1k.preview.tigrisdata.cloud is a serverless deployment with builtin automatic database sharding, meaning that, unlike MongoDB Atlas, you never have to worry about sharding or shard keys, and the data distribution is automatically handled.

mongosh mongodb://your_client_id:your_client_secret@m1k.preview.tigrisdata.cloud:27018/?authMechanism=PLAIN --quiet --tls

You will see output similar to the following:

test>

Create the database​

Let's create our database mongosh_quickstart

use mongosh_quickstart

You will see output similar to following:

test> use mongosh_quickstart
switched to db mongosh_quickstart

Create a collection and insert a document​

Let's create the collection podcasts and insert a document

db.podcasts.insertOne({
  title: 'The Polyglot Developer Podcast',
  author: 'Nic Raboy',
  tags: [ 'development', 'programming', 'coding' ]
})

This results in the following output:

mongosh_quickstart> db.podcasts.insertOne({ title: 'The Polyglot Developer Podcast', author: 'Nic Raboy', tags: [ 'development', 'programming', 'coding' ] })
{
  acknowledged: true,
  insertedId: ObjectId("63f8340c6fdb0db31a94bcbf")
}

We can see that the collection is created:

mongosh_quickstart> show collections
podcasts

Read all documents in the collection​

Let's now read the data in the collection:

db.podcasts.find()

This returns all the documents in the collection podcasts:

mongosh_quickstart> db.podcasts.find()
[
  {
    _id: ObjectId("63f8340c6fdb0db31a94bcbf"),
    title: 'The Polyglot Developer Podcast',
    author: 'Nic Raboy',
    tags: [ 'development', 'programming', 'coding' ]
  }
]
