e-commerce platform backend, can serve as a base for projects which consumes mongodb documents and advanced filters. As well as GridFS for uploading and retrieving files.

1. Install miniconda latest version(This will install conda, a package and environment manager)

   • https://docs.conda.io/en/latest/miniconda.html

2. Update conda just in case,

   • conda update conda

3. Create the environment using the file macmod-environment.yml file using the following command,

   • conda env create -f macmod-environment.yml

4. Activate the environment,

   • conda activate "env name"

1. Install the new package in your environment using

   • conda install "packagename"
   • pip install "packagename"

2. Add the package name and the version in the macmod-environment.yml file

   (put the package under respective package manager)

3. Push the updated environment file to git.

1. git pull the environment file.

2. update your current environment using

   • conda env update -f macmod-environment.yml

   This will automatically check the differences in your current file and install the new ones.

1. install mongodb from the following source:

   • sudo apt update
   • sudo apt install mongodb-org

2. Check the installation:

   • mongod --version

3. Connect to the db with the command:

   • mongo mongodb://localhost:27017

4. Use the admin database:

   • use admin

5. create a new user for use in the backend with the following command:

   * db.createUser(

   {

   user:"useradmin", pwd:"<password>", roles: [{ role:"userAdminAnyDatabase", db:"admin" }]

   }

   )

6. Enable database security in the file mongod.conf:

   • security:

     authorization: "enabled"

7. Create database replace the [] values with the names for database and collection:

   • use [new-database-name]
   • and insert a value in a custom collection: db.[collection-name].insert({ Name : "TecAdmin.net" })

8. List the existing databases:

   • show dbs;

9. for finish set the database environment variables with this structure:

   export DATABASE_HOST="localhost" export DATABASE_PORT=27017 export DATABASE_NAME=[database-name] export DATABASE_USERNAME=[database-username] export DATABASE_PASSWORD=[database-password]

10. command to import json array to database from command line: mongoimport --host --ssl --username <username> --password <password> --authentication <clustername-uri> admin --db <DATABASE> --collection <COLLECTION> --jsonArray <PATH TO FILE>

NOTES: applications pdfs are stored in fs.files and contain 'brand' metadata key: example: { _id: asdf, filename: "somefile", metadata: {filename: "somefile", brand: "ace"}}

all other content is stored in fs.files and will contain 'content' metadata key:

example1: { _id: asdf, filename: "someotherfile", metadata: {filename: "someotherfile", content: "Whitepaper"}}, example2: { _id: asdf, filename: "randomfile", metadata: {filename: "randomfile", content: "Lab notes"}}
