Check out the projects I am currently working on, by sliding to the next page. To add new projects, I am using a form which stores data in an aws DynamoDB table.

Go ahead and add a project (only to the frontend), by clicking the button below.

dev journal

I developed this project with three things in mind:

#1 to learn - new tools, skills, technologies, ways of doing things, you name it - and to deepen the knowledge I already have;

#2 to track - I'm a big fan of "journaling" as both a way to keep track of one's progress, and a way of storing ideas and resources that could be reused later;

#3 to give you - a potential employer - an idea about my skills and work routine.

These are the projects I'm currently developing:

— This is the project you are currently browsing through :).

I am very excited about it because I didn't use any of the code provided by Spiced during the bootcamp, but instead it's the result of my further post-Spiced learning.

Although still work in progress, it's taking shape with every feature I'm implementing.

Learning how to work with serverless framework and a tiny part of the aws ecosystem was both challenging - with peaks of frustration and lows of desperation - and highly rewarding - when something works, you're just walking on clouds.

Situation: when my SPA loads, I want to fetch two things from the backend: 1. the dates of all the entries in the journal-entries-table, so I can map them on the timeline on the right side of the page, and 2. the most recent entry in the db. For the most recent entry I added the date as the sort key. The links below are two very good explanations.

/date/ is a reserved keyword in DynamoDB, so my query was throwing an error. I therefore had to use an Expression Attribute Name to substitute the name of the key. And it's working!!

axios
TO REMEMBER FOREVER AND EVER: axios API for DELETE method is different than for GET or POST. I spent hours debugging perfectly good code, just to find out that the way I pass data to the body is different. /// here I need to have an area with text as code -> to work on that in the next days.

You cannot query a dynamoDB table based only on the sort key. You need either a composite primary key (partition + sort) or set a GSI, which is the solution I'm going for because I it allows me to only update the table, I don't need to redefine the schema (to redefine the KeySchema I have to remove the table from the yaml file and add it again, which also deletes the table and all the data in it).

I added another http event trigger to my getJournalEntry function because I want to be able to use the /journal-entry API resource both with and without path parameters.

To create another global secondary index I would need to define another key attribute. To avoid this, I will find a solution on the frontend: from the list of journal entry dates I will get the most recent and then make a request with that date as a path parameter to the /journal-entry/{journalEntryDate} endpoint.
