logging the development of an interplanetary filesystem
WIP
Starlog is a way of publishing a blog-type feed, without requiring any specific servers to store it. This is accomplished through IPFS content addressable data structures.
Each user running the app for the first time, will be asked to initialize a feed. This is done by checking if the local ipns name points to an object with {"type": "starlog"} encoded as JSON in the data portion of the object.
The root starlog object has a data portion with the name of the log, and also a link to the actual data structure representation of the log.
It can optionally also contain a link to an image, used as the blog icon.
A Finger Tree is used to store the log entries. This is an append-only version of this structure, requiring no balancing. This layout of data allows constant time access to the first and last elements of the feed.
See also krl/aolog.
Search is implemented by taking the text of the entries in the leaves of the tree, and construct a bloom filter out of them.
When you search for one or more words, they are also made into a (very sparse) bloom filter. You can then check this against whole subtrees, and throw them away if they give a negative.
WARNING, these special settings are for development only, and are concidered unsafe for normal ipfs usage.
Starlog uses both npm and Bower to install dependencies. If you do not have them, you'll need to install them first.
bower install
npm installMake sure your ipfs daemon is running with API_ORIGIN set to 'http://localhost:8082', and using --unrestricted-api:
API_ORIGIN="http://localhost:8082" ipfs daemon --unrestricted-apiLeave that running, and then run the following in a new console window:
$ npm run serve
# open in localhost:8082-
npm run serve- Opens the app in your local browser on 8082, redirects/ipfsand/apicalls to your ipfs daemon on port 5001. -
npm run local- Packs up the app with vulcanize, adds it to ipfs, and opens the resulting hash in your local api gateway. -
npm run gateway- Packs the app up and runs it from the ipfs.io gateway.
Feel free to join in. All welcome. Open an issue!
