save string to ipfs local gateway browser

To save a string to an IPFS local gateway from a browser, you can use the ipfs-http-client library in a web application. First, install the library and the buffer polyfill using npm or yarn. Then, configure the client to connect to your local IPFS node running a gateway on http://localhost:8080. Use the create function from ipfs-http-client to initialize the client with the local gateway's host and port. Once the client is set up, you can use the add method to upload the string. For example, const added = await client.add('hello world') will add the string to IPFS and return a response containing the content identifier (CID). The resulting CID can be used to retrieve the string via the local gateway using a URL like http://localhost:8080/ipfs/{cid}. This approach leverages the local gateway to interact with the IPFS network without relying on public gateways.

The HTTP to IPFS Gateway - Explained · GitHub

Folks who run a local ipfs daemon can use their own gateway, at https://localhost:8080 by default, to allow their browser and other tools to fetch content-addressed data over http but using their ipfs node to find and fetch it.

Lesson: Use an HTTP browser to retrieve files from local IPFS gateway · GitBook

You can use a local IPFS node to read content from the worldwide IPFS network. The two ways of interacting with your local node are 1) through the command line and 2) through the HTTP gateway. You can use either of those interfaces to pass IPFS the content-addressed (hash) identifiers of the content you want.

For example, some browsers or tools like Curl (opens new window) or Wget (opens new window) don't support IPFS natively and cannot access to IPFS content using canonical addressing like ipfs://{CID}/{optional path to resource}. While tools like IPFS Companion add browser support for native IPFS URLs, this is not always an option. As such, IPFS gateways enable a broad range of applications to interface with IPFS using HTTP. ... Recursive vs. non-recursive gateways · Trusted vs. trustless gateways ... Regardless of who deploys a gateway and where, any IPFS gateway resolves access to any requested IPFS content identifier. Your machine may host a gateway as a local service; e.g., at localhost:8080.

You can use the official js-ipfs-api library. Then you can use the ipfs.files.add function to post your file, since you already have it in an array buffer. If that doesnt work, the js-ipfs-api has a built in Buffer object you can use.

You should probably use the Gateway API instead of the Node API. Just POST a file to it, you'll get a hash back.

For an example, see how IPFessay does it.

About the IPFS.io Public Gateway

An IPFS gateway acts as a bridge between the traditional web protocol (HTTP) and the IPFS protocol. It listens for requests for IPFS content, retrieves that content via IPFS, and makes it available via HTTP. This allows anyone to access content from public IPFS networks, no matter what web browser they're using.

Your gateway hostname will be the Hostname value you supplied when you created the gateway. The request path will vary based on the type of content you are serving. If a request path is /ipfs/<CID_HASH>, that tells the gateway that you want the content with the Content Identifier (CID) that immediately follows.

August 11, 2022 - HTTP Gateway was created as something IPFS node exposes on localhost or in a trusted LAN. In these contexts, double verification brings unnecessary overhead, and by default one wants to get re-assembled bytes back, without IPFS/IPLD envelopes. The ability to request a block or CAR stream from a public gateway was introduced earlier this year to enable verifiable retrieval in more constrained contexts, like IoT, web worker CDNs, or mobile browsers.

It also takes a screenshot with the tabs.captureVisibleTab API and finally saves the object to local storage + IPFS. I also hit another tricky issue that I'm unsure of how to solve. Current implementation is naive in that it assumes that URLs mostly end up being the same content for all users, which is not true. Sometimes web applications renders data into JS files (hurr) and served as normal scripts. ... I know the pain: we can't even use MHTML as it is not supported by browser vendors (anymore).

Is a gateway only for uploading to IPFS? In other words, if a gateway is shut down, is a file (say NFT) lost from the system? Thanks!

Edit: thanks all for the help!!
