ATP API
This API is a client for ATProtocol servers. It communicates using HTTP. It includes:
- ✔️ APIs for ATProto and Bluesky.
- ✔️ Validation and complete typescript types.
- ✔️ Session management.
- ✔️ A RichText library.
Getting started
First install the package:
yarn add @atproto/api
Then in your application:
import { BskyAgent } from '@atproto/api'
const agent = new BskyAgent({ service: 'https://example.com' })
Usage
Session management
Log into a server or create accounts using these APIs. You'll need an active session for most methods.
import { BskyAgent, AtpSessionEvent, AtpSessionData } from '@atproto/api'
const agent = new BskyAgent({
service: 'https://example.com',
persistSession: (evt: AtpSessionEvent, sess?: AtpSessionData) => {
// store the session-data for reuse
}
})
await agent.login({identifier: '[email protected]', password: 'hunter2'})
await agent.resumeSession(savedSessionData)
await agent.createAccount({
email: '[email protected]',
password: 'hunter2',
handle: 'alice.example.com'
})
API calls
The agent includes methods for many common operations, including:
// Feeds and content
await agent.getTimeline(params, opts)
await agent.getAuthorFeed(params, opts)
await agent.getPostThread(params, opts)
await agent.getPost(params)
await agent.getPosts(params, opts)
await agent.getLikes(params, opts)
await agent.getRepostedBy(params, opts)
await agent.post(record)
await agent.deletePost(postUri)
await agent.like(uri, cid)
await agent.deleteLike(likeUri)
await agent.repost(uri, cid)
await agent.deleteRepost(repostUri)
await agent.uploadBlob(data, opts)
// Social graph
await agent.getFollows(params, opts)
await agent.getFollowers(params, opts)
await agent.follow(did)
await agent.deleteFollow(followUri)
// Actors
await agent.getProfile(params, opts)
await agent.upsertProfile(updateFn)
await agent.getProfiles(params, opts)
await agent.getSuggestions(params, opts)
await agent.searchActors(params, opts)
await agent.searchActorsTypeahead(params, opts)
await agent.mute(did)
await agent.unmute(did)
// Notifications
await agent.listNotifications(params, opts)
await agent.countUnreadNotifications(params, opts)
await agent.updateSeenNotifications()
// Identity
await agent.resolveHandle(params, opts)
await agent.updateHandle(params, opts)
// Session management
await agent.createAccount(params)
await agent.login(params)
await agent.resumeSession(session)
Validation and types
The package includes a complete types system which includes validation and type-guards. For example, to validate a post record:
import { AppBskyFeedPost } from '@atproto/api'
const post = {...}
if (AppBskyFeedPost.isRecord(post)) {
// typescript now recognizes `post` as a AppBskyFeedPost.Record
// however -- we still need to validate it
const res = AppBskyFeedPost.validateRecord(post)
if (res.success) {
// a valid record
} else {
// something is wrong
console.log(res.error)
}
}
Rich text
Some records (ie posts) use the app.bsky.richtext
lexicon. At the moment richtext is only used for links and mentions, but it will be extended over time to include bold, italic, and so on.
ℹ️ It is strongly recommended to use this package's RichText
library. Javascript encodes strings in utf16 while the protocol (and most other programming environments) use utf8. Converting between the two is challenging, but RichText
handles that for you.
import {RichText} from '@atproto/api'
// creating richtext
const rt = new RichText({text: 'Hello @alice.com, check out this link: https://example.com'})
await rt.detectFacets(agent) // automatically detects mentions and links
const postRecord = {
$type: 'app.bsky.feed.post',
text: rt.text,
facets: rt.facets,
createdAt: new Date().toISOString()
}
// rendering as markdown
let markdown = ''
for (const segment of rt.segments()) {
if (segment.isLink()) {
markdown += `[${segment.text}](${segment.link?.uri})`
} else if (segment.isMention()) {
markdown += `[${segment.text}](https://my-bsky-app.com/user/${segment.mention?.did})`
} else {
markdown += segment.text
}
}
// calculating string lengths
const rt2 = new RichText({text: 'Hello'})
console.log(rt2.length) // => 5
console.log(rt2.graphemeLength) // => 5
const rt3 = new RichText({text: '👨👩👧👧'})
console.log(rt3.length) // => 25
console.log(rt3.graphemeLength) // => 1
Advanced
Advanced API calls
The methods above are convenience wrappers. It covers most but not all available methods.
The AT Protocol identifies methods and records with reverse-DNS names. You can use them on the agent as well:
const res1 = await agent.com.atproto.repo.createRecord(
{
did: alice.did,
collection: 'app.bsky.feed.post',
record: {
$type: 'app.bsky.feed.post',
text: 'Hello, world!',
createdAt: new Date().toISOString()
}
}
)
const res2 = await agent.com.atproto.repo.listRecords({repo: alice.did, collection: 'app.bsky.feed.post'})
const res3 = await agent.app.bsky.feed.post.create({repo: alice.did}, {
text: 'Hello, world!',
createdAt: new Date().toISOString()
})
const res4 = await agent.app.bsky.feed.post.list({repo: alice.did})
Generic agent
If you want a generic AT Protocol agent without methods related to the Bluesky social lexicon, use the AtpAgent
instead of the BskyAgent
.
import { AtpAgent } from '@atproto/api'
const agent = new AtpAgent({service: 'https://example.com'})
Non-browser configuration
In non-browser environments you'll need to specify a fetch polyfill. See the example react-native polyfill here.
import { BskyAgent } from '@atproto/api'
const agent = new BskyAgent({service: 'https://example.com'})
// provide a custom fetch implementation (shouldnt be needed in node or the browser)
import {AtpAgentFetchHeaders, AtpAgentFetchHandlerResponse} from '@atproto/api'
BskyAgent.configure({
async fetch(
httpUri: string,
httpMethod: string,
httpHeaders: AtpAgentFetchHeaders,
httpReqBody: any,
): Promise<AtpAgentFetchHandlerResponse> {
// insert definition here...
return {status: 200, /*...*/}
}
})
