The Journey of #100DaysOfCode (@sourabhbagrecha)

Hi everybody,
I have heard a lot about #100daysof code. Yesterday was the 100th & final day for my colleagues(@Kushagra_Kesav & @henna.s).
After seeing them making consistent progress and learning while they were doing the challenge, I am quite impressed and motivated to do the same.
Hence, I have decided that I will take the baton from here and will start my journey of 100daysofcode from today.

I will be sharing my daily updates in the form of a Medium blog summarizing the things that I have learned during the day.

Wish me luck :crossed_fingers:.

Yesterday, we had a MongoDB User Group hosted at our MongoDB India Office.

While I was summarizing all the things I learned in the past 8 days I fell asleep midway because I was very tired after all the fun we had, so here I am, approximately 17(I usually post around 2-3 am) hours late to the party.
But, better late than never, here’s the summary of all the things I learned in the past 8 days.

No worries, you are initiator of the party.

#Day15 of #100daysofcode

Today I learned about:

  • How to initialize a React App from the bare React Native CLI
  • How to enable Atlas Device Sync
  • How to initialize a Realm instance in React Native the right way
  • I also gave expo another chance to build RN apps, but seems like I am gonna stick with Bare RN CLI, because the flexibility to choose any library we want is very limited in the expo environment.

I will extend my expengo web app to Mobile devices as well. Using Atlas Device Sync I will try to provide a smooth user experience by creating a RN app that will work even when the device is not connected to the internet.

I will try to finish building this app by the weekend, and hopefully, we will have a brand new blog by then.

Weekend :rocket: finally! Today I finished watching the second season of Panchayat, the last episode was very emotional, but overall it was so fun, really enjoyed it.

In terms of the things I learned today, I made some progress on connecting the Local Realm on React Native with MongoDB’s Atlas Device Sync. Got some errors due to Expense schema not found, I guess I may have made an incorrect configuration therefore I will be making the required changes on the MongoDB Cloud tomorrow.

#Day18 of #100daysofcode

Today I finally fixed the following error:

Figured out it was a very silly mistake on my end, I added the schema array to the sync config options object but it has to be a key of the parent config options object. I also had to verify my schema from the Realm SDK tab from the left panel of the MongoDB App Services Dashboard.
Now I am finally able to read and sync all of my data from the MongoDB Cloud to my iOS Simulator.
I am currently struggling to find a good React Native UI library that can provide components and other UI elements out of the box so that I don’t have to write CSS on my own.
I also added the CreateExpense form and page and configured the same in ReactNavigation.
