get: async

Get a message by its hash-id.

get {msgid}

get(msgid, cb)

createFeedStream: source

(feed) Fetch messages ordered by their claimed timestamps.

feed
  [--live]
  [--gt index]
  [--gte index]
  [--lt index]
  [--lte index]
  [--reverse] 
  [--keys]
  [--values]
  [--limit n]

createFeedStream({
  live:,
  gt:,
  gte:,
  lt:,
  lte:,
  reverse:,
  keys:,
  values:,
  limit:,
  fillCache:,
  keyEncoding:,
  valueEncoding:
})

Create a stream of the data in the database, ordered by the timestamp claimed by the author. NOTE - the timestamp is not verified, and may be incorrect. The range queries (gt, gte, lt, lte) filter against this claimed timestap.

• live (boolean, default: false): Keep the stream open and emit new messages as they are received.
• gt (greater than), gte (greater than or equal) define the lower bound of the range to be streamed. Only records where the key is greater than (or equal to) this option will be included in the range. When reverse=true the order will be reversed, but the records streamed will be the same.
• lt (less than), lte (less than or equal) define the higher bound of the range to be streamed. Only key/value pairs where the key is less than (or equal to) this option will be included in the range. When reverse=true the order will be reversed, but the records streamed will be the same.
• reverse (boolean, default: false): a boolean, set true and the stream output will be reversed. Beware that due to the way LevelDB works, a reverse seek will be slower than a forward seek.
• keys (boolean, default: true): whether the data event should contain keys. If set to true and values set to false then data events will simply be keys, rather than objects with a key property.
• values (boolean, default: true): whether the data event should contain values. If set to true and keys set to false then data events will simply be values, rather than objects with a value property.
• limit (number, default: -1): limit the number of results collected by this stream. This number represents a maximum number of results and may not be reached if you get to the end of the data first. A value of -1 means there is no limit. When reverse=true the highest keys will be returned instead of the lowest keys.
• fillCache (boolean, default: false): wheather LevelDB's LRU-cache should be filled with data read.
• keyEncoding / valueEncoding (string): the encoding applied to each read piece of data.

createLogStream: source

(log) Fetch messages ordered by the time received.

log
  [--live]
  [--gt index]
  [--gte index]
  [--lt index]
  [--lte index]
  [--reverse] 
  [--keys]
  [--values]
  [--limit n]

createLogStream({ 
  live:,
  gt:,
  gte:,
  lt:,
  lte:,
  reverse:,
  keys:,
  values:,
  limit:,
  fillCache:,
  keyEncoding:,
  valueEncoding:
})

Creates a stream of the messages that have been written to this instance, in the order they arrived. The objects in this stream will be of the form:

{ key: Hash, value: Message, timestamp: timestamp }

timestamp is the time which the message was received. It is generated by monotonic-timestamp. The range queries (gt, gte, lt, lte) filter against this receive timestap.

• live (boolean, default: false): Keep the stream open and emit new messages as they are received.
• gt (greater than), gte (greater than or equal) define the lower bound of the range to be streamed. Only records where the key is greater than (or equal to) this option will be included in the range. When reverse=true the order will be reversed, but the records streamed will be the same.
• lt (less than), lte (less than or equal) define the higher bound of the range to be streamed. Only key/value pairs where the key is less than (or equal to) this option will be included in the range. When reverse=true the order will be reversed, but the records streamed will be the same.
• reverse (boolean, default: false): a boolean, set true and the stream output will be reversed. Beware that due to the way LevelDB works, a reverse seek will be slower than a forward seek.
• keys (boolean, default: true): whether the data event should contain keys. If set to true and values set to false then data events will simply be keys, rather than objects with a key property.
• values (boolean, default: true): whether the data event should contain values. If set to true and keys set to false then data events will simply be values, rather than objects with a value property.
• limit (number, default: -1): limit the number of results collected by this stream. This number represents a maximum number of results and may not be reached if you get to the end of the data first. A value of -1 means there is no limit. When reverse=true the highest keys will be returned instead of the lowest keys.
• fillCache (boolean, default: false): wheather LevelDB's LRU-cache should be filled with data read.
• keyEncoding / valueEncoding (string): the encoding applied to each read piece of data.

messagesByType: source

(logt) Retrieve messages with a given type, ordered by receive-time.

logt
  --type {type}
  [--live]
  [--gt index]
  [--gte index]
  [--lt index]
  [--lte index]
  [--reverse] 
  [--keys]
  [--values]
  [--limit n]

messagesByType({
  type:,
  live:,
  gt:,
  gte:,
  lt:,
  lte:,
  reverse:,
  keys:,
  values:,
  limit:,
  fillCache:,
  keyEncoding:,
  valueEncoding:
})

All messages must have a type, so this is a good way to select messages that an application might use. Like in createLogStream, the range queries (gt, gte, lt, lte) filter against the receive timestap.

• type (string): The type of the messages to emit.
• live (boolean, default: false): Keep the stream open and emit new messages as they are received.
• gt (greater than), gte (greater than or equal) define the lower bound of the range to be streamed. Only records where the key is greater than (or equal to) this option will be included in the range. When reverse=true the order will be reversed, but the records streamed will be the same.
• lt (less than), lte (less than or equal) define the higher bound of the range to be streamed. Only key/value pairs where the key is less than (or equal to) this option will be included in the range. When reverse=true the order will be reversed, but the records streamed will be the same.
• reverse (boolean, default: false): a boolean, set true and the stream output will be reversed. Beware that due to the way LevelDB works, a reverse seek will be slower than a forward seek.
• keys (boolean, default: true): whether the data event should contain keys. If set to true and values set to false then data events will simply be keys, rather than objects with a key property.
• values (boolean, default: true): whether the data event should contain values. If set to true and keys set to false then data events will simply be values, rather than objects with a value property.
• limit (number, default: -1): limit the number of results collected by this stream. This number represents a maximum number of results and may not be reached if you get to the end of the data first. A value of -1 means there is no limit. When reverse=true the highest keys will be returned instead of the lowest keys.
• fillCache (boolean, default: false): wheather LevelDB's LRU-cache should be filled with data read.
• keyEncoding / valueEncoding (string): the encoding applied to each read piece of data.

createHistoryStream: source

(hist) Fetch messages from a specific user, ordered by sequence numbers.

hist {feedid} [seq] [live]
hist --id {feedid} [--seq n] [--live]

createHistoryStream(id, seq, live)
createHistoryStream({ id:, seq:, live: })

createHistoryStream and createUserStream serve the same purpose. createHistoryStream exists as a separate call because it provides fewer range parameters, which makes it safer for RPC between untrusted peers.

• id (FeedID, required): The id of the feed to fetch.
• seq (number, default: 0): If seq > 0, then only stream messages with sequence numbers greater than seq.
• live (boolean, default: false): Keep the stream open and emit new messages as they are received.

createUserStream: source

Fetch messages from a specific user, ordered by sequence numbers.

createUserStream
  --id {feedid}
  [--live]
  [--gt index]
  [--gte index]
  [--lt index]
  [--lte index]
  [--reverse] 
  [--keys]
  [--values]
  [--limit n]

createUserStream({ 
  id:,
  live:,
  gt:,
  gte:,
  lt:,
  lte:,
  reverse:,
  keys:,
  values:,
  limit:,
  fillCache:,
  keyEncoding:,
  valueEncoding:
})

createHistoryStream and createUserStream serve the same purpose. createHistoryStream exists as a separate call because it provides fewer range parameters, which makes it safer for RPC between untrusted peers.

The range queries (gt, gte, lt, lte) filter against the sequence number.

• id (FeedID, required): The id of the feed to fetch.
• live (boolean, default: false): Keep the stream open and emit new messages as they are received.
• gt (greater than), gte (greater than or equal) define the lower bound of the range to be streamed. Only records where the key is greater than (or equal to) this option will be included in the range. When reverse=true the order will be reversed, but the records streamed will be the same.
• lt (less than), lte (less than or equal) define the higher bound of the range to be streamed. Only key/value pairs where the key is less than (or equal to) this option will be included in the range. When reverse=true the order will be reversed, but the records streamed will be the same.
• reverse (boolean, default: false): a boolean, set true and the stream output will be reversed. Beware that due to the way LevelDB works, a reverse seek will be slower than a forward seek.
• keys (boolean, default: true): whether the data event should contain keys. If set to true and values set to false then data events will simply be keys, rather than objects with a key property.
• values (boolean, default: true): whether the data event should contain values. If set to true and keys set to false then data events will simply be values, rather than objects with a value property.
• limit (number, default: -1): limit the number of results collected by this stream. This number represents a maximum number of results and may not be reached if you get to the end of the data first. A value of -1 means there is no limit. When reverse=true the highest keys will be returned instead of the lowest keys.
• fillCache (boolean, default: false): wheather LevelDB's LRU-cache should be filled with data read.
• keyEncoding / valueEncoding (string): the encoding applied to each read piece of data.

links: source

Get a stream of messages, feeds, or blobs that are linked to/from an id.

links
  [--source id|filter]
  [--dest id|filter]
  [--rel value]
  [--keys]
  [--values]
  [--live]
  [--reverse]

links({
  source:,
  dest:,
  rel:,
  keys:,
  values:,
  live:,
  reverse:
})

The objects in this stream will be of the form:

{ source: ID, rel: String, dest: ID, key: MsgID }

• source (string, optional): An id or filter, specifying where the link should originate from. To filter, just use the sigil of the type you want: @ for feeds, % for messages, and & for blobs.
• dest (string, optional): An id or filter, specifying where the link should point to. To filter, just use the sigil of the type you want: @ for feeds, % for messages, and & for blobs.
• rel (string, optional): Filters the links by the relation string.
• live (boolean, default: false): Keep the stream open and emit new messages as they are received.
• reverse (boolean, default: false): a boolean, set true and the stream output will be reversed. Beware that due to the way LevelDB works, a reverse seek will be slower than a forward seek.
• keys (boolean, default: true): whether the data event should contain keys. If set to true and values set to false then data events will simply be keys, rather than objects with a key property.
• values (boolean, default: true): whether the data event should contain values. If set to true and keys set to false then data events will simply be values, rather than objects with a value property.

relatedMessages: async

Retrieve the tree of messages related to the given id.

relatedMessages
  --id {msgid}
  [--rel value]
  [--count]
  [--parent]

relatedMessages ({ id:, rel:, count:, parent: }, cb)

This is ideal for collecting things like threaded replies. The output is a recursive structure like this:

{
  key: <id>,
  value: <msg>,
  related: [
    <recursive>,...
  ],

  // number of messages below this point.
  // (when opts.count = true)
  count: <int>,

  // the message this message links to.
  // this will not appear on the bottom level.
  // (when opts.parent = true)
  parent: <parent_id>
}

• id (MsgID): Root message, fetches messages related message to its ID.
• rel (string, optional): Filters the links by the relation string.
• count (boolean, default: false): Include a count of each message's decendant messages.
• parent (boolean, default: false): Include the parent id of each message.

add: async

Add a well-formed message to the database.

cat ./message.json | add
add
  --author {feedid}
  --sequence {number}
  --previous {msgid}
  --timestamp {number}
  --hash sha256
  --signature {sig}
  --content.type {type}
  --content.{...}

add({
  author:,
  sequence:,
  previous: timestamp:,
  hash: 'sha256',
  signature:,
  content: { type:, ... },
}, cb)

• author (FeedID): Public key of the author of the message.
• sequence (number): Sequence number of the message. (Starts from 1.)
• previous (MsgID): Hash-id of the previous message in the feed (null for seq=1).
• timestamp (number): Unix timestamp for the publish time.
• hash (string): The hash algorithm used in the message, should always be sha256.
• signature (string): A signature computed using the author pubkey and the content of the message (less the signature attribute).
• content (object): The content of the message.
  • .type (string): The object's type.

publish: async

Construct a message using sbot's current user, and add it to the DB.

cat ./message-content.json | publish
publish --type {string} [--other-attributes...]

publish({ type:, ... }, cb)

This is the recommended method for publishing new messages, as it handles the tasks of correctly setting the message's timestamp, sequence number, previous-hash, and signature.

• content (object): The content of the message.
  • .type (string): The object's type.
