install

Install as a dependency:

$ npm i -S @planetary-ssb/pub

Install as an app (git clone):

$ git clone git@github.com:planetary-social/planetary-pub.git pub

use

cli

$ node ./index.js

node

var createSbot = require('@planetary-ssb/pub/pub')
var Viewer = require('@planetary-ssb/pub/viewer')

createSbot((err, sbot) => {
  if (err) throw err
  var viewer = Viewer(sbot)
  viewer.listen(PORT, '0.0.0.0', (err, address) => {
      if (err) return cb(err)
      console.log(`Server is now listening on ${address}`)
  })
})

git hooks

We're using husky to automatically run tests and lint when you push to the 'main' branch.

push without running tests

git push --no-verify

setup git hooks

Add the test script as a git hook. This way we can check which branch we're on in the git hook.

npx husky add .husky/pre-push "./test/githook/prepush.sh"

test

Test the viewer

NODE_ENV=test node test/viewer.js | npx tap-spec

Test the pub

NODE_ENV=test node test/index.js | npx tap-spec

Start the pub locally, using real data, not test-data

NODE_ENV=staging-local node index.js

Use a 512 MB limit on memory (so you can tell if it uses too much)

NODE_ENV=staging-local node --max-old-space-size=512 index.js

Start the debugger, viewable in chrome:

NODE_ENV=staging-local node --inspect-brk --max-old-space-size=512 index.js

then open chrome://inspect/

Connect to your pub

In another terminal/machine:

// need to get this address from the other sbot
var addr = 'net:localhost:62042~shs:LYknR3SSOEOrXD2yEQcHhIrUQmsPNo5+3ETvfjuf3Mw='

// the `ssb-conn` plugin
sbot.conn.connect(addr, (err, ssb) => {
  if (err) return console.log('errrrr', err)
  console.log('**connected to pub**', !!ssb)
})

env variables

See .env.example

NODE_ENV="test"
FAUNA_SECRET="123"
TEST_PW="my-password"

---

Set NODE_ENV to test to re-write the DB with test data when the server starts.

$ NODE_ENV=test npm start

Set NODE_ENV to staging to automatically connect to and follow the pubs in ./pubs.json.

$ NODE_ENV=staging npm start

A NODE_ENV of staging-local means that you will connect to and follow other pubs automatically like above, but the DB will use a different directory, db-staging. Because that way you can run tests on your local machine using the db folder, and also make a pub that uses the folder db-staging for data that is more real.

$ NODE_ENV=staging-local npm start

http API

These are the endpoints available if you call the http API

/

=> sbot.id | NODE_ENV

example

/ =>

address -- net:localhost:62042~shs:LYknR3SSOEOrXD2yEQcHhIrUQmsPNo5+3ETvfjuf3Mw=
public keys -- @LYknR3SSOEOrXD2yEQcHhIrUQmsPNo5+3ETvfjuf3Mw=.ed25519
NODE_ENV -- test

/:message-id

=> thread of messages related to that id, or just the message with id

example

/%1HbhmsEc4OCiLD5o8raRl+x8QUO7Y6oZ3C57vwNM78c=.sha256

/blob/:blobId

=> return a blob, indexed by blob hash

example

/blob/&SNZQDvykMENRmJMVyLfG20vlvgelGwj03C3YjWEi0JQ=.sha256

/feed/:userName

get a feed by display name. will return an array of JSON messages
