The file added by node.js can't be get/cat on other nodes

Type: Question

Severity: Medium

Description: I can't find the file that I added by node.js, I used to get the file by

node1 -> ipfs.io gateway (use https://ipfs.io/ipfs/--hash--) -> node2
but when I use this way to transfer files previous times, I failed.
I can't cat my files on the ipfs.io gateway(use https://ipfs.io/ipfs/--hash--)
Is there other way to transfer files from node1 to node2 by hash, or has some tips to solve my problem?
I want to use a node to add files and another node to get files on the node.js
thanks!!!!!

Steps to reproduce the error:

@kappabooom I'm not sure if I understood fully your question, but if I did, your answer is on the Project Status - https://github.com/ipfs/js-ipfs#project-status

Essentially, until we have DHT fully working -- #856 -- you have to be the one connecting the nodes directly.

@diasdavid thanks, did you mean that if I want to get files from another node, I need to connecting to the node first? is there an example, because I'm not sure if I fully understood your reply QQ

[kappabooom]

besides, when I run the example(https://github.com/ipfs/js-ipfs/tree/master/examples/ipfs-101).
while I change the 'hello.txt' in 1.js by another txt, I won't cat the new file. Is it means that I can't add files to IPFS network currently?

[daviddias]

@kappabooom I think you are trying multiple cases there and finding a couple of caveats.

js-ipfs doesn't run the DHT by default, the DHT is the secret sauce that enables IPFS to find content on the network seamlessly.

js-ipfs will try to find other nodes and will connect to the gateways, so any content that is on the gateway is discoverable.

For example, If you boot 2 js-ipfs nodes in the browser, you will be able to exchange data between them because will discover each other and dial through WebRTC.

Follow the DHT PR for more updates :)

@diasdavid thanks for your reply :) I am more clear about DHT and js-ipfs.
But I still have some trouble on use example ipfs-101

@kappabooom the issue you had with 101 was due to #973 (the infrastructure of IPFS changed), now that is fixed with 0.25.4 release. Have fun! :)
