Guide on loading numerous JavaScript files into a database using the mongo shell

I am faced with the task of loading multiple js files that contain collections creations and seeds into my database using the mongo command. Currently, I have been manually loading data from each file one by one like so:

mongo <host>:<port>/<database> -u <user> -p <password> < db.users.js

However, as the number of files increases, I am looking for a more efficient way to load all of them at once into mongo, preferably using the mongo shell. Is there a streamlined method to accomplish this?

Answer №1

There are various methods to execute these files. I have a pair of js files called first_script.js and second_script.js, for instance.

When using the operating system command line, you can specify all the files like this:

mongo localhost/testdb first_script.js second_script.js

Alternatively, you can combine all the scripts into one js file. Create a file named combined_script.js with the following contents:

load("first_script.js")
load("second_script.js")

To run the combined script, use the following command:

mongo localhost/testdb combined_script.js

An alternative approach to executing multiple scripts from within the mongo shell is as follows:

> const script_files = [ "first_script.js", "second_script.js" ]
> for (let file of script_files) {
      load(file)
  }
