Add a file using api

[aniket-kumar]

I want to create a webpage in which user will upload a file and that file will be uploaded on ipfs and i will get the hash of file internally. I think i can do this using the apis of ipfs but i didn't get any particular documentation of ipfs apis. Tell me, How can i solve this purpose?

[aniket-kumar]

@harshetha I am not able to see your comment. I think your response can help a lot to solve this issue. Thanks in advance

[harshetha]

I am working on a web scenario where I have to upload a file into ipfs and
then retrieve the document hash. I am working off of this code I have
linked but it is not fully functional, just a general idea of how to call
functions from the ipfs api using Node.js.
ipfs-inactive/examples#17
Let me know if you find something further and I will do the same

I have tried multiple approaches found from anywhere but none of them is working to upload a file. Yeah, i come to learn how to upload text only. I don't know if any api of ipfs is made for this purpose.

[harshetha]

Can I see how you uploaded text? Maybe I can add some commands and combine
my knowledge to figure out how to upload a file.

I just followed this :
https://www.npmjs.com/package/ipfs-js

let me know about any progress... :)

[harshetha]

I have tried this before but it did not work for me, can I see your code
and file structure?

Thanks

It was also not working on my system but when i uploaded it to ipfs and executed it from ipfs then it worked for me. Try that. Follow all the steps given in that link till 4th one.

[aniket-kumar]

@harshetha any progress?

[harshetha]

No, the issue is that the files.add function is not yet implemented in the
index.js or the load-commands.js (these files are called in the ipfs api),
we either need to write our own function or find someone's fork that
already has it.

yeah, you are right. I was also thinking same.

[harshetha]

ok, let me know about any progress...go ahead

[RichardLitt]

@diasdavid Can you answer this?

[daviddias]

You can upload a file to IPFS using the js-ipfs-api(HTTP Client Library, works with Go or JS IPFS nodes) or js-ipfs (Full node in JS) using the interface defined here https://github.com/ipfs/interface-ipfs-core#files

Try first using https://github.com/ipfs/js-ipfs-api and the go-ipfs daemon and let me know of your results. Note that you will have to set the CORS headers this way https://github.com/ipfs/js-ipfs-api#cors

[aniket-kumar]

@diasdavid i tried this js-ipfs-api. It is working fine for ipfs.id but when i tried to use ipfs.add("string").then(callback) , it showed the error : Uncaught TypeError: ipfs.add is not a function

[daviddias]

@aniket-kumar, try with ipfs.files.add

[aniket-kumar]

@diasdavid now new error : Uncaught TypeError: cb is not a function in add.js
I am trying to add the string as ipfs.files.add("hey") . I also tried it with hex and binary format of string. It is giving the same error.

[aniket-kumar]

@harshetha @RichardLitt @diasdavid any new findings?

[ttaveira]

I'm trying to do the same thing. If I understand correctly, ipfs.files.add requires a Bufferor Readable Stream (Node.js types). Are we able to use the js-ipfs-api without Node?

Also, is there any difference between ipfs.files.add and ipfs.add?

[neuronsupport]

ipfs-js is node.js only I guess. If we could not write/move/copy/delete files from web browser in a way, how would ipfs be useful to anyone other than showing static web pages.

[victorb]

@aniket-kumar

You have two different ways of using the ipfs.files.add method. Either you define a callback like this:

ipfs.files.add([new Buffer('hello world')], (err, res) => {
// do something with res
})

Or use it with promises:

ipfs.files.add([new Buffer('hello world')]).then((res) => {
// do something with res
}).catch((err) => { /* handle err */ })

It's mentioned in the readme over here: https://github.com/ipfs/js-ipfs-api#callbacks-and-promises

@ttaveira

Are we able to use the js-ipfs-api without Node?

Yes, it works in the browser as well. You have some examples here: https://github.com/ipfs/js-ipfs-api/tree/master/examples

Also, is there any difference between ipfs.files.add and ipfs.add?

No, it's merely there to fulfill the interface we defined in https://github.com/ipfs/interface-ipfs-core/ while remaining backwards compatibility.

@norzak No, js-ipfs works in the browser as well. There are examples in the repository itself (here: https://github.com/ipfs/js-ipfs/tree/master/examples) and I've also made an example for passing around data you can check out here: https://github.com/VictorBjelkholm/js-ipfs-passing-data

I'm gonna close this issue, and refer to future readers to open up issues in the appropriate repository if you're having any troubles with either js-ipfs or js-ipfs-api

We are leaving issues open in FAQ repo so they are more easily visible.
