Learning GraphQL from a Video

I tried to do this without a blog post and I failed. Look. It's HARD having such a unique learning style. It's harder still trying to explain it to people. GraphQL is a way to use existing tools. With Rest API, you might have to hit multiple endpoints. You might have to re-hit endpoints with multiple parameters based on information you get back from prior queries.

You might get far more information than you need. GraphQL from what I understand allows you to just hit one endpoint to get the information you need. And you can specify different parameters and things that you want etc. All to get back exactly what you want. This feels very magical. Very magical indeed. Right.

So this is the video I am watching:


It will of course take me much longer than 40 minutes to watch this - and that is okay. I learn slower, but I learn thoroughly. So this video has an example.

The example 

In the example, we have to build an app. We have two inputs - authors and books. 

Each one has lots and lots of information.

The thing is for each of these we only want to display one thing - names. 

So we want to get each of the authors - and only their names. And then we want to get each of the books by author - and only their name too. Doing this with Rest API from the API is a long and painful process. But I have just got to the bit where he shows how to do it with GraphQL. Thanks. 

With GraphQL, you compose a query, of exactly the data that you want

"WITH GRAPHQL, YOU COMPOSE A QUERY, OF EXACTLY THE DATA THAT YOU WANT." With Graph QL you compose a query of exactly the data that you want - thank you

Oh man

Okay so - you write your query in such a way that you say - this is what I want: I want to query authors -> and I just want the names. And then for every author -> I want to query books -> and then I just want the names. And YOU WILL GET THIS BACK. And NOTHING ELSE

You will get ONLY THE INFORMATION THAT YOU ASKED FOR

And you can get AS MUCH INFORMATION AS YOU WANT. Or AS LITTLE INFORMATION AS YOU WANT. THANKS

I have to leave it there for now. I don't know whether to continue with the video or not. I have been coding along. I will ask my mentor. I was going to read some docs. I ran out of time but I can read them later

I love my life so so much

I am so lucky

and thank you <3 ❤️❤️❤️

Hello World

 Hello from Susanna Codes! Hi everyone,  My name is Susanna and I'm a 28-year-old aspiring software engineer from Brighton! As I type this, listening to music from "Le Fabuleux Destin d'Amelie Poulain" (it reminds me of home, in Luxembourg, where I am from - I'm missing home quite a lot lately!) and look forward to some Irish Cream tea in my afternoon break, I am thinking: How lucky I am that my amazing colleague Rosana helped me out with a plan for my software engineer journey (she directed me to the front-end first). How HTML and CSS would not have been my first languages of choice had I not been guided in this direction, as in my head they were seen as 'less-serious' langages. How done I am with what other people think of me and if other people see the 'front-end' as softer then so be it! Everyone has to start somewhere. I am so grateful to be on this journey, with Codecademy's Front-End Engineer Career Path.  Thank you to Async Brighton as ...

“But yesterday, I heard God say, you were born to be the one…”

“But yesterday, I heard God say, you were born to be the one…” Hey there. Still off work. Still tired. Lana del Rey released a new song. Thank God. My soul needed it so much.  I’m thinking a lot about everything. Thinking about where I went wrong. I just want to release. I want to release all the crap that is in my room. I’ve been trying to fully declutter since I was 21. I give away so much. I donate so much. But then I never quite finish. I never get to the click. And then I buy more. I don’t know what technique to use. There are so many techniques. The Marie Kondo method. I like to do kinaesthetic tests too. I like to pretend I’m packing up during the pandemic again and I have to make really quick decisions about what to keep and what to leave behind. That was no fun. But it was efficient. I just can’t release it. There’s so much stuff I can’t let go of. I don’t know how to. I don’t know how to. I suppose that’s a good metaphor for life. We accumulate stuff and we hold on to it....

In the Water, I find Fire

In the Water, I find Fire Who am I without renewable energy? I had to ask myself this question last year when my company laid off half its employees.  I didn’t know who I was anymore. Not without renewable energy. But I did everything I could to stay in it. The time in between jobs allowed me to experiment. Travel around the UK a bit. Reconnect with old hobbies. Rediscover my femininity a bit - be someone who wasn’t always working. But I fought to stay in renewable energy. A part of myself has been telling myself that I am in renewable energy still and that’s great because I am. But I am mostly in water. And that was hard for me to accept that. Because I love renewable energy so so much. And I couldn’t imagine my life without it. But now I can. Not because I don’t love it But because I need to give myself to something more too and that is water Because in the water I find my passion In the water, I find my fire In the water, I find my self again In the water, I find my Self So let’...
