Thank you for the tutorial! The example at 8:42 is not working for me. First I need to use double quotes and after doing this I am getting the error "Invalid value provided for argument `where`: Object({\"token0\": Object({\"symbol\": String(\"ETH\")})})" Did it worked for you?
Haha, shit I'm having that same problem. Seems unable to filter tokens by symbol. I can't imagine that is true. It has to be a syntax error on our part, but I'll have to look into it.
I want to get all the entries from an entity in the mapping file. Like let's suppose I have created an entity called Transaction. When a particular event is triggered, I want to reset values for some particular transactions. How can I get all the entries, better if I can provide a filter in event handler?
Great video, thanks! I have a question. I have to create a schema for querying all Transfer events for a specific address. How can I pass the address in the schema? Thank you in advance.
That's because of what he mentions at 2:40. There are two distinct categories for subgraphs; some are on the hosted/centralized network and do not require an API key and are free to query from, while others are on the decentralized network and require you to setup an API key and pay for your queries (typically under/around 0.00003 GRT per query as of writing this). Usually a subgraph on the decentralized network is also on hosted-service, so it's really a matter of whether you value decentralization and relying on a hosted service vs. a larger distributed network of indexers
You will need to index data and create an API for this yourself or check the major Blockchain API (Coingecko, etc..) to see if they offer this, but I am not sure about that.
hi is there an easy way to query what my position is in a uniswap v2 pool given my wallet public key address? I tried using GraphQL, but I'm having a hard time. Basically, I was to pass my wallet public key address, and have it return my position: ETH: 1.5 USDC: 4500 (when ETH price is 3000). Many Thanks.
When I run code "npm script.j" console show following error "TypeError: Cannot read property 'flashLoans' of undefined" Anyone knows how to fix it ? Thank you
Hi Khash, It's not a course, it's a 1h coaching I can give you advice for various things like technical questions about Blockchain or advice for your career as a Blockchain developer. For my courses, this is a different thing: eattheblocks.com/6-figure-blockchain-developer eattheblocks-pro.teachable.com/p/profitable-flashloans Cheers
@@EatTheBlocks done :) You explain from the begging the arguments and it is soo good. Don’t change anything. You are the traversy media for the Blockchain
This is the best tutorial out there for theGraph!
Agreed
Thanks for sharing. This is finally a simple and clear guide on how to query in general with GraphQL
Glad you liked it
Great video, very informative. The graph seems like a cool protocol
This video is the most helpful resource for querying Uniswap with GRT
Thanks for explaining in a simple way
Glad it helped

This also doesn't work for me. Is there any solution for query with token symbol?
Haha, shit I'm having that same problem. Seems unable to filter tokens by symbol. I can't imagine that is true. It has to be a syntax error on our part, but I'll have to look into it.
@@just10joy please tell me any of you guys found a solution :(
{
tokens(where: {
symbol: "WETH"
}){
whitelistPairs{
token0{
symbol
}
token1{
symbol
}
}
}
}
this is for sushiswap btw

another great video.

11:01 - how to use The Graph from NodeJS app
seem interesting, but how to use with ganache? local ethereum maybe?
Thanks so much for this.

Awesome video, thanks!
Can u do a tutorial how to become a subgrapher?! Thank you!
Nice video thank you. I picked another subgraph to query from axios and noticed in the copied URL they require an API key. Why you didnt require one?

Can you explain why data I pull from the query is so different than the DEX's own analytics?
cool video,
Thank you for this tutorial!!
is this free ?
gr8 content, Thank you.
Can we query based on contract/ wallet address? I don't see that there :/
many same pair address displayed? how to fix this please
Can you please do a video on creating subgraphs? Thanks!
maybe later :)
@@EatTheBlocks please do!
you can find some already
cest gratuit ?
This helped so much, thank you!!!
Glad it helped!
@EatTheBlocks
Receiving the following error:
'No value provided for required argument: `id`'. Kindly suggest a possible solution..
this is cool, sir I want more
Thanks Paul!
Can you tell me how can i get the OHLC for the Uniswap and other defi platforms
You will need to index data and create an API for this yourself or check the major Blockchain API (Coingecko, etc..) to see if they offer this, but I am not sure about that.
Great tutorial- keep it up
Thanks!
I'm getting a 403 error with the applied example, any ideas what's going wrong?

Hi nice Video. Can you Tell me how to create a trading view out of this .
no idea :(

Hello Julian, I am thinking about taking your 1 on 1 couching course. My question is how long does the course lasts.?
Hi Khash,

Why didn't this video get recommended to me earlier :(
can you tell me about the playground web site
its on the website of the graph
What are the difference between The Graph, Covalent and Infura ? (except the GraphQL part wich is obvious)
Infura is centralized and uses a REST API, Thegraph is decentralized and use a GraphQL API
@@EatTheBlocks thank you for your answer !
Cool bro! I’m italian and I understand all
haha I am glad Italian friends can follow as well :)

This doesnt work for me
no such thing as first or job or x figure or how or get or etc, cepuxyuax, do, can do any nmw and any s perfx
Dear Julien, Could you please help us with your knowledge on how can we extract/export the blockchainn data using Ethreum etl github library
centralized solution. good luck. they totally misunderstood whole thing
