If you know me, you know I am an Invisible Internet Project [#I2P] enthusiast. (See the https://geti2p.net/ #homepage.) I2P is similar to Tor, but differs in that _every_ client instance of the I2P software, while connected to the Internet, _participates in routing traffic_ around Internet blockages.

I just read https://www.diva.exchange/en/privacy/i2p-interview-with-the-developer-idk-part-2/ and came across a link to a #SoftwareLibrary for the "SAM API" of I2P. In the past, I had thought the SAM #API cumbersome and clunky (perhaps this was due to the format of the documentation).

The https://www.diva.exchange/ team have created a #Typescript wrapper for the I2P SAM API. It seems that Diva Exchange uses #I2PD (the #CPlusPlus variety of the available I2P applications) rather than the reference #Java implementation.

**If you are affiliated with diva.exchange/, please reach out to the editors to include back-links to the I2P Homepage and #SourceCode repositories & documentation!** Even if the links are subtle and get overlooked by casual readers (attentive readers will cite the links additionally), the publicity gained by linking to the relevant I2P pages _should_ help the I2P to climb the ranks of search engine results. Mutual aid is a social duty — even on the Internet!

> Blizzard is a standalone version of the Tor Project’s Snowflake proxy. It can be used to produce an I2P Plugin that will donate a Snowflake to Tor Browser users. The Snowflake uses I2P to manage its lifecycle. That means when you start and stop your I2P router you start and stop the Snowflake.
