What is mongoDB dbpath?

Where is the database folder?

- You should be able to find the location in the configuration file : /etc/mongod.conf

grep dbPath /etc/mongod/conf

grep???

-grep searches for PATTERNS in  each FILE. PATTERNS is one or patterns separated by newline charactors, and grep prints each line that matches a pattern.

If the default path is not given, mongo saves the data in the root directory
as printed when grep dbPath /etc/mongodb/conf shows

:  dbPath: /var/lib/mongodb

otherwise, I can set a default path to save the data.

from Mongodb :

If you want mongod to store data files at a path other than /data/db you can specify a dbPath. The dbPath must exist before you start mongod. If it does not exist, create the directory and the permissions so that mongod can read and write data to this path. For more information on permissions, see the security operations documentation.

JS 5.7 task5 Store read dates

<HTML>   <body>   </body>    <script>    let messages = [        {text: "Hello", from: "John"},        {text: "How goes?", from: "John"},        {text: "See you soon", from: "Alice"}    ];    let readMap = new WeakMap();    alert(readMap.size);    readMap.set(messages[0], new Date(2019, 3, 5));   </script> </HTML> <!-- task4 needed weakSet to save simply readmessage, this task needs to save THE TIME IT WAS READ along with the message itself the message out of the set or map means it hasn't been read I kinda feel good and bad at the same time to happen to read the solution but I do get to think more about the difference with tasks and be more available to understand the main contents so I think, its good? -->

How to set base url when deployed in Heroku? : base url and axios

https://stackoverflow.com/questions/47164330/axios-api-calls-in-heroku/47165888 baseUrl = process.env.baseURL || "http://localhost:5000" Even more stable way https://stackoverflow.com/questions/52129849/how-to-get-the-base-url-variable-on-a-deployed-heroku-node-app const production  = 'https://examplePage.com'; const development = 'http://localhost:3000/'; const url = (process.env.NODE_ENV ? production : development); process.env.NODE_ENV will resolve to undefined if you are running on localhost production mode. and return production if you have deployed the app production mode.
