How to mongoimport in a remote server

Question

I'm trying to create a simple website that displays a table based on a relatively small json data (>5MB). I plan on importing the json into MongoDB and performing queries using a driver (either Mongoose or PyMongo). As the data size is very small, I'd like to avoid using the cloud service so that I only pay for the server costs.

I've tried to familiarize myself with mongoimport by trying that on my local machine. I was successful in importing the data locally but now I'd like to do this on the remote server.

How would you do this on a remote server? As I understand, mongod should be running in the background to start mongo or mongoimport. How do you achieve this with one window? Is there a guide that any of you found helpful in doing this type of a job?

Answer 1

You can directly use the official mongoimport command, from a shell.

Below a full example :

mongoimport -h localhost:27018 -d developer-database -c developer-collection -u root -p root --authenticationDatabase admin --file data-local.json

You can add the option --jsonArray if you json contains an array.

You can add the option --type csv, if your file is not a json but a csv.

Since your data size is small, I'd recommend using MongoDB Atlas. Create a cluster and mongoimport using the URI which can be found within your cluster (Connect --> Connect Your Application --> Connection String Only).

To mongoimport,

mongoimport --uri "URI" --drop --collection collectionName --file localFileLocation

where you need to specify: 1) "URI" 2) collectionName 3) localFileLocation.

Once the mongoimport works, you can query the cloud data via Mongo shell after fetching the connection string (Connect --> Connect with the Mongo Shell --> Connection String Only)

mongo "connectionString" --username yourUsername

where you need to specify: 1) "connectionString" 2) yourUsername.

Now, type in your password associated with the cluster you created, then you should be connected and ready to query data held in Mongo Atlas from the command line.
