please help me "ipfs result" not returnig any value.. i waited more than a hour still no result ipfs.add() not working... please help me ... thanks in advance🙏🙏🙏
@@bhaskardutta3470 Think this will work out for you - npm install ipfs-http-client@33.1.1 - instead of installing the latest version try to install the exact version of this video
Great video!! What would now be interesting is the following thing: Think of 3 users. User 1 and user 2 are already granted access to the page. When user 3 wants to sign up he has to send a request to the other 2 users. They can then decide on the rights of user 3 (reading and/or writing). Depending on the rights of user 3 - he is only allowed to see or even to change the current meme. In a second step ( (and I think this is where Blockchain gets interesting) we could keep track of the changes: When user 3 changes the meme, the blockchain should tell us who and when the meme was changed. The change should be tracked on the blockchain. We can trust the blockchain as an immutable storage and if user 3 denies that he has changed the meme, we can proove him wrong........ Are you gonna do some kind of this in any of the upcoming videos? Like "How to Build Ethereum Dapp With IPFS 2.0 " ?
I tried to submit but I got the following error: Failed to load resource: the server responded with a status of 401 (Unauthorized), anybody that can help me
Seems I'm having issues with my request timing out. No matter what I do I can't get a response from IPFS other than `Request timed out`. Anyone else getting this?
Yes..this is probably because IPFS is very unstable. I have searched multiple forums for this problem. It seems to be a problem that appears only in the gateway, though. Also, I noticed that the request time fluctuates. I am messing around with IPFS the last 6 months, and I noticed that some times there is no delay on the requests. I hope that helps! :) If you find something more, feel free to share!

@@ratchaponpockathum3683 Make sure that you shouldn't use single quotes where you're mentioning the gateway, you have to use the symbol that's there below esc key on the keyboard, the key before key number 1.

run "npm install" -- all nodejs repos should keep the node_modules out of the repo since they should be built by your machine. the binaries in there will vary based on your system architecture, hence the need to run npm install.
github will never store node_modules because thats where all your dependencies are which takes up a lot of memory. so always npm install when you clone a github repo which grabs the dependencies specified in your package.json file

I like that you jump from json, js, react, ipfs, and sol and still make it pedagogical. :) Well done.
Absolutely love how and when you use the documentation. :) Less googeling and more RTFM.
So basically you replace the backend & database with IPFS & Ethereum.

You could try using another IPFS gateway like

this.setState({memeHash: `gateway.ipfs.io/ipfs/${memeHash}`}) ..` if you type in the gateway in onSubmit, then in HTML content, image tag will look like this
