### what's new
12
+
## 0.1.0
8
13
9
-
**sync types** - enums from `com.atproto.sync.subscribeRepos` lexicon:
14
+
sync types for firehose consumption:
10
15
11
16
- `CommitAction` - `.create`, `.update`, `.delete`
12
17
- `EventKind` - `.commit`, `.sync`, `.identity`, `.account`, `.info`
13
18
- `AccountStatus` - `.takendown`, `.suspended`, `.deleted`, `.deactivated`, `.desynchronized`, `.throttled`
14
19
15
-
these integrate with zig's `std.json` for automatic parsing. define struct fields as enums instead of strings, and get exhaustive switch checking.
16
-
17
-
### migration
18
-
19
-
if you're currently doing string comparisons:
20
-
21
-
```zig
22
-
// before: string comparisons everywhere
23
-
const TapRecord = struct {
24
-
action: []const u8,
25
-
collection: []const u8,
26
-
// ...
27
-
};
28
-
29
-
if (mem.eql(u8, rec.action, "create") or mem.eql(u8, rec.action, "update")) {
30
-
// handle upsert
31
-
} else if (mem.eql(u8, rec.action, "delete")) {
32
-
// handle delete
33
-
}
34
-
```
35
-
36
-
switch to enum fields:
37
-
38
-
```zig
39
-
// after: type-safe enums
40
-
const TapRecord = struct {
41
-
action: zat.CommitAction, // parsed automatically by std.json
42
-
collection: []const u8,
43
-
// ...
44
-
};
45
-
46
-
switch (rec.action) {
47
-
.create, .update => processUpsert(rec),
48
-
.delete => processDelete(rec),
49
-
}
50
-
```
51
-
52
-
the compiler enforces exhaustive handling - if AT Protocol adds a new action, your code won't compile until you handle it.
53
-
54
-
**this is backwards compatible.** your existing code continues to work. adopt the new types when you're ready.
55
-
56
-
### library overview
57
-
58
-
zat provides zig primitives for AT Protocol:
59
-
60
-
| feature | description |
61
-
|---------|-------------|
62
-
| string primitives | `Tid`, `Did`, `Handle`, `Nsid`, `Rkey`, `AtUri` - parsing and validation |
63
-
| did resolution | resolve `did:plc` and `did:web` to documents |
64
-
| handle resolution | resolve handles to DIDs via HTTP well-known |
65
-
| xrpc client | call AT Protocol endpoints (queries and procedures) |
66
-
| sync types | enums for firehose consumption |
67
-
| json helpers | navigate nested json without verbose if-chains |
68
-
| jwt verification | verify service auth tokens (ES256, ES256K) |
69
-
| multibase/multicodec | decode public keys from DID documents |
70
-
71
-

# zat publishes its own docs to ATProto
2
+
3
+
zat uses itself to publish these docs as `site.standard.document` records. here's how.
4
+
5
+
## the idea
6
+
7
+
i'm working on [search for leaflet](https://leaflet-search.pages.dev/) and more generally, search for [standard.site](https://standard.site/) records. many are [currently thinking about how to facilitate better idea sharing on atproto right now](https://bsky.app/profile/eugenevinitsky.bsky.social/post/3mbpqpylv3s2e).
8
+
9
+
this is me doing a rep of shipping a "standard.site", so i know what i'll be searching through, and to better understand why blogging platforms choose their schema extensions etc for i start indexing/searching their record types.
10
+
11
+
## what we built
12
+
13
+
a zig script ([`scripts/publish-docs.zig`](https://tangled.sh/zat.dev/zat/tree/main/scripts/publish-docs.zig)) that:
14
+
15
+
1. authenticates with the PDS via `com.atproto.server.createSession`
16
+
2. creates a `site.standard.publication` record
17
+
3. publishes each doc as a `site.standard.document` pointing to that publication
18
+
4. uses deterministic TIDs so records get the same rkey every time (idempotent updates)
19
+
20
+
## the mechanics
21
+
22
+
### TIDs
23
+
24
+
timestamp identifiers. base32-sortable. we use a fixed base timestamp with incrementing clock_id so each doc gets a stable rkey:
25
+
26
+
```zig
27
+
const pub_tid = zat.Tid.fromTimestamp(1704067200000000, 0); // publication
28
+
const doc_tid = zat.Tid.fromTimestamp(1704067200000000, i + 1); // docs get 1, 2, 3...
29
+
```
30
+
31
+
### CI
32
+
33
+
[`.tangled/workflows/publish-docs.yml`](https://tangled.sh/zat.dev/zat/tree/main/.tangled/workflows/publish-docs.yml) triggers on `v*` tags. tag a release, docs publish automatically.
34
+
35
+
`putRecord` with the same rkey overwrites, so the CI job overwrites `standard.site` records when you cut a tag.

# zat - expanded scope
6
+
7
+
the initial release delivered string primitives (Tid, Did, Handle, Nsid, Rkey, AtUri). this plan expands toward a usable AT Protocol sdk.
8
+
9
+
## motivation
10
+
11
+
real-world usage shows repeated implementations of:
12
+
- DID resolution (plc.directory lookups, did:web fetches)
13
+
- JWT parsing and signature verification
14
+
- ECDSA verification (P256, secp256k1)
15
+
- base58/base64url decoding
16
+
- XRPC calls with manual json navigation
17
+
18
+
this is shared infrastructure across any atproto app. zat can absorb it incrementally.
19
+
20
+
## next: did resolution
21
+
22
+
```zig
23
+
pub const DidResolver = struct {
24
+
/// resolve a did to its document
25
+
pub fn resolve(self: *DidResolver, did: Did) !DidDocument
26
+
27
+
/// resolve did:plc via plc.directory
28
+
fn resolvePlc(self: *DidResolver, id: []const u8) !DidDocument
29
+
30
+
/// resolve did:web via .well-known
31
+
fn resolveWeb(self: *DidResolver, domain: []const u8) !DidDocument
32
+
};
33
+
34
+
pub const DidDocument = struct {
35
+
id: Did,
36
+
also_known_as: [][]const u8, // handles
37
+
verification_methods: []VerificationMethod,
38
+
services: []Service,
39
+
40
+
pub fn pdsEndpoint(self: DidDocument) ?[]const u8
41
+
pub fn handle(self: DidDocument) ?[]const u8
42
+
};
43
+
```
44
+
45
+
## next: cid (content identifiers)
46
+
47
+
```zig
48
+
pub const Cid = struct {
49
+
raw: []const u8,
50
+
51
+
pub fn parse(s: []const u8) ?Cid
52
+
pub fn version(self: Cid) u8
53
+
pub fn codec(self: Cid) u64
54
+
pub fn hash(self: Cid) []const u8
55
+
};
56
+
```
57
+
58
+
## later: xrpc client
59
+
60
+
```zig
61
+
pub const XrpcClient = struct {
62
+
pds: []const u8,
63
+
access_token: ?[]const u8,
64
+
65
+
pub fn query(self: *XrpcClient, nsid: Nsid, params: anytype) !JsonValue
66
+
pub fn procedure(self: *XrpcClient, nsid: Nsid, input: anytype) !JsonValue
67
+
};
68
+
```
69
+
70
+
## later: jwt verification
71
+
72
+
```zig
73
+
pub const Jwt = struct {
74
+
header: JwtHeader,
75
+
payload: JwtPayload,
76
+
signature: []const u8,
77
+
78
+
pub fn parse(token: []const u8) ?Jwt
79
+
pub fn verify(self: Jwt, public_key: PublicKey) bool
80
+
};
81
+
```
82
+
83
+
## out of scope
84
+
85
+
- lexicon codegen (separate project)
86
+
- session management / token refresh (app-specific)
87
+
- jetstream client (websocket.zig + json is enough)
88
+
- application frameworks (too opinionated)
89
+
90
+
## design principles
91
+
92
+
1. **layered** - each piece usable independently (use Did without DidResolver)
93
+
2. **explicit** - no hidden allocations, pass allocators where needed
94
+
3. **borrowing** - parse returns slices into input where possible
95
+
4. **fallible** - return errors/optionals, don't panic
96
+
5. **protocol-focused** - AT Protocol primitives, not app-specific features
97
+
98
+
## open questions
99
+
100
+
- should DidResolver cache? or leave that to caller?
101
+
- should XrpcClient handle auth refresh? or just expose tokens?
102
+
- how to handle json parsing without imposing a specific json library?

# zat - zig atproto primitives
6
+
7
+
low-level building blocks for atproto applications in zig. not a full sdk - just the pieces that everyone reimplements.
8
+
9
+
## philosophy
10
+
11
+
from studying the wishlists: the pain is real, but the suggested solutions often over-engineer. we want:
12
+
13
+
1. **primitives, not frameworks** - types and parsers, not http clients or feed scaffolds
14
+
2. **layered design** - each piece usable independently
15
+
3. **zig idioms** - explicit buffers, comptime validation, no hidden allocations
16
+
4. **minimal scope** - solve the repeated pain, not every possible need
17
+
18
+
## scope
19
+
20
+
### in scope (v0.1)
21
+
22
+
**tid** - timestamp identifiers
23
+
- parse tid string to timestamp (microseconds)
24
+
- generate tid from timestamp
25
+
- extract clock id
26
+
- comptime validation of format
27
+
28
+
**at-uri** - `at://did:plc:xyz/collection/rkey`
29
+
- parse to components (did, collection, rkey)
30
+
- construct from components
31
+
- validation
32
+
33
+
**did** - decentralized identifiers
34
+
- parse did:plc and did:web
35
+
- validate format
36
+
- type-safe wrapper (not just `[]const u8`)
37
+
38
+
### maybe v0.2
39
+
40
+
**facets** - extract links/mentions/tags from post records
41
+
- given a json value with `text` and `facets`, extract urls
42
+
- byte-offset handling for utf-8
43
+
44
+
**cid** - content identifiers
45
+
- parse cid strings
46
+
- validate format
47
+
48
+
### out of scope (for now)
49
+
50
+
- lexicon codegen (too big, could be its own project)
51
+
- xrpc client (std.http.Client is fine)
52
+
- session management (app-specific)
53
+
- jetstream client (websocket.zig exists, just wire it)
54
+
- feed generator framework (each feed is unique)
55
+
- did resolution (requires http, out of primitive scope)
56
+
57
+
## design
58
+
59

66
+
pub fn parse(s: []const u8) ?Tid
67
+
68
+
/// timestamp in microseconds since unix epoch
69
+
pub fn timestamp(self: Tid) u64
70
+
71
+
/// clock identifier (lower 10 bits)
72
+
pub fn clockId(self: Tid) u10
73
+
74

/// generate tid for current time
75

pub fn now() Tid
76

77

/// generate tid for specific timestamp
78

pub fn fromTimestamp(ts: u64, clock_id: u10) Tid
79

80

/// format to string
81

pub fn format(self: Tid, buf: *[13]u8) void
82

};
83
+
```
84

151
+
152
+
```zig
153
+
// in root.zig, uncomment to promote:
154
+
pub const Tid = internal.Tid;
155
+
```
156
+
157
+
users who need bleeding-edge access can always use:
158
+
159
+
```zig
160
+
const zat = @import("zat");
161
+
const tid = zat.internal.Tid.parse("...");
162
+
```
163
+
164
+
this pattern exists indefinitely - even after 1.0, new experimental features start in internal.
165
+
166
+
## decisions
167
+
168
+
### why not typed lexicons?
169
+
170
+
codegen from lexicon json is a big project on its own. the core pain (json navigation) can be partially addressed by documenting patterns, and the sdk should work regardless of how people parse json.
171
+
172
+
### why not an http client wrapper?
173
+
174
+
zig 0.15's `std.http.Client` with `Io.Writer.Allocating` works well. wrapping it doesn't add much value. the real pain is around auth token refresh and rate limiting - those are better solved at the application level where retry logic is domain-specific.
175
+
176
+
### why not websocket/jetstream?
177
+
178
+
websocket.zig already exists and works well. the jetstream protocol is simple json messages. a thin wrapper doesn't justify a dependency.
179
+
180
+
### borrowing vs owning
181
+
182
+
for parse operations, we borrow slices into the input rather than allocating. callers who need owned data can dupe. this matches zig's explicit memory style.
183
+
184
+
## next steps
185
+
186
+
1. ~~implement tid.zig with tests~~ done
187
+
2. ~~implement at_uri.zig with tests~~ done
188
+
3. ~~implement did.zig with tests~~ done
189
+
4. ~~wire up build.zig as a module~~ done
190
+
5. try using it in find-bufo or music-atmosphere-feed to validate the api
191
+
6. iterate on internal APIs based on real usage
192
+
7. promote stable APIs to root.zig

# zat - expanded scope
2
-
3
-
the initial release delivered string primitives (Tid, Did, Handle, Nsid, Rkey, AtUri). this plan expands toward a usable AT Protocol sdk.
4
-
5
-
## motivation
6
-
7
-
real-world usage shows repeated implementations of:
8
-
- DID resolution (plc.directory lookups, did:web fetches)
9
-
- JWT parsing and signature verification
10
-
- ECDSA verification (P256, secp256k1)
11
-
- base58/base64url decoding
12
-
- XRPC calls with manual json navigation
13
-
14
-
this is shared infrastructure across any atproto app. zat can absorb it incrementally.
15
-
16
-
## next: did resolution
17
-
18
-
```zig
19
-
pub const DidResolver = struct {
20
-
/// resolve a did to its document
21
-
pub fn resolve(self: *DidResolver, did: Did) !DidDocument
22
-
23
-
/// resolve did:plc via plc.directory
24
-
fn resolvePlc(self: *DidResolver, id: []const u8) !DidDocument
25
-
26
-
/// resolve did:web via .well-known
27
-
fn resolveWeb(self: *DidResolver, domain: []const u8) !DidDocument
28
-
};
29
-
30
-
pub const DidDocument = struct {
31
-
id: Did,
32
-
also_known_as: [][]const u8, // handles
33
-
verification_methods: []VerificationMethod,
34
-
services: []Service,
35
-
36
-
pub fn pdsEndpoint(self: DidDocument) ?[]const u8
37
-
pub fn handle(self: DidDocument) ?[]const u8
38
-
};
39
-
```
40
-
41
-
## next: cid (content identifiers)
42
-
43
-
```zig
44
-
pub const Cid = struct {
45
-
raw: []const u8,
46
-
47
-
pub fn parse(s: []const u8) ?Cid
48
-
pub fn version(self: Cid) u8
49
-
pub fn codec(self: Cid) u64
50
-
pub fn hash(self: Cid) []const u8
51
-
};
52
-
```
53
-
54
-
## later: xrpc client
55
-
56
-
```zig
57
-
pub const XrpcClient = struct {
58
-
pds: []const u8,
59
-
access_token: ?[]const u8,
60
-
61
-
pub fn query(self: *XrpcClient, nsid: Nsid, params: anytype) !JsonValue
62
-
pub fn procedure(self: *XrpcClient, nsid: Nsid, input: anytype) !JsonValue
63
-
};
64
-
```
65
-
66
-
## later: jwt verification
67
-
68
-
```zig
69
-
pub const Jwt = struct {
70
-
header: JwtHeader,
71
-
payload: JwtPayload,
72
-
signature: []const u8,
73
-
74
-
pub fn parse(token: []const u8) ?Jwt
75
-
pub fn verify(self: Jwt, public_key: PublicKey) bool
76
-
};
77
-
```
78
-
79
-
## out of scope
80
-
81
-
- lexicon codegen (separate project)
82
-
- session management / token refresh (app-specific)
83
-
- jetstream client (websocket.zig + json is enough)
84
-
- application frameworks (too opinionated)
85
-
86
-
## design principles
87
-
88
-
1. **layered** - each piece usable independently (use Did without DidResolver)
89
-
2. **explicit** - no hidden allocations, pass allocators where needed
90
-
3. **borrowing** - parse returns slices into input where possible
91
-
4. **fallible** - return errors/optionals, don't panic
92
-
5. **protocol-focused** - AT Protocol primitives, not app-specific features
93
-
94
-
## open questions
95
-
96
-
- should DidResolver cache? or leave that to caller?
97
-
- should XrpcClient handle auth refresh? or just expose tokens?
98
-
- how to handle json parsing without imposing a specific json library?

# zat - zig atproto primitives
2
-
3
-
low-level building blocks for atproto applications in zig. not a full sdk - just the pieces that everyone reimplements.
4
-
5
-
## philosophy
6
-
7
-
from studying the wishlists: the pain is real, but the suggested solutions often over-engineer. we want:
8
-
9
-
1. **primitives, not frameworks** - types and parsers, not http clients or feed scaffolds
10
-
2. **layered design** - each piece usable independently
11
-
3. **zig idioms** - explicit buffers, comptime validation, no hidden allocations
12
-
4. **minimal scope** - solve the repeated pain, not every possible need
13
-
14
-
## scope
15
-
16
-
### in scope (v0.1)
17
-
18
-
**tid** - timestamp identifiers
19
-
- parse tid string to timestamp (microseconds)
20
-
- generate tid from timestamp
21
-
- extract clock id
22
-
- comptime validation of format
23
-
24
-
**at-uri** - `at://did:plc:xyz/collection/rkey`
25
-
- parse to components (did, collection, rkey)
26
-
- construct from components
27
-
- validation
28
-
29
-
**did** - decentralized identifiers
30
-
- parse did:plc and did:web
31
-
- validate format
32
-
- type-safe wrapper (not just `[]const u8`)
33
-
34
-
### maybe v0.2
35
-
36
-
**facets** - extract links/mentions/tags from post records
37
-
- given a json value with `text` and `facets`, extract urls
38
-
- byte-offset handling for utf-8
39
-
40
-
**cid** - content identifiers
41
-
- parse cid strings
42
-
- validate format
43
-
44
-
### out of scope (for now)
45
-
46
-
- lexicon codegen (too big, could be its own project)
47
-
- xrpc client (std.http.Client is fine)
48
-
- session management (app-specific)
49
-
- jetstream client (websocket.zig exists, just wire it)
50
-
- feed generator framework (each feed is unique)
51
-
- did resolution (requires http, out of primitive scope)
52
-
53
-
## design
54

63
-
64
-
/// timestamp in microseconds since unix epoch
65
-
pub fn timestamp(self: Tid) u64
66
-
67

75
-
76
-
/// format to string
77
-
pub fn format(self: Tid, buf: *[13]u8) void
78
-
};
79
-
```
80
-
81
-
encoding: base32-sortable (chars `234567abcdefghijklmnopqrstuvwxyz`), 13 chars, first 11 encode 53-bit timestamp, last 2 encode 10-bit clock id.
82

84
-
85
-
```zig

# roadmap
2
+
3
+
zat started as a small set of string primitives for AT Protocol - the types everyone reimplements (`Tid`, `Did`, `Handle`, `Nsid`, `Rkey`, `AtUri`). the scope grew based on real usage.
4
+
5
+
## history
6
+
7
+
**initial scope** - string primitives with parsing and validation. the philosophy: primitives not frameworks, layered design, zig idioms, minimal scope.
8
+
9
+
**what grew from usage:**
10
+
- DID resolution was originally "out of scope" - real projects needed it, so `DidResolver` and `DidDocument` got added
11
+
- XRPC client and JSON helpers - same story
12
+
- JWT verification for service auth
13
+
- handle resolution via HTTP well-known
14
+
- handle resolution via DNS-over-HTTP (community contribution)
15
+
- sync types for firehose consumption (`CommitAction`, `EventKind`, `AccountStatus`)
16
+
17
+
this pattern - start minimal, expand based on real pain - continues.
18
+
19
+
## now
20
+
21
+
use zat in real projects. let usage drive what's next.
22
+
23
+
the primitives are reasonably complete. what's missing will show up when people build things. until then, no speculative features.
24
+
25
+
## maybe later
26
+
27
+
these stay out of scope unless real demand emerges:
28
+
29
+
- lexicon codegen - probably a separate project
30
+
- higher-level clients/frameworks - too opinionated
31
+
- token refresh/session management - app-specific
32
+
- feed generator scaffolding - each feed is unique
33
+
34
+
## non-goals
35
+
36
+
zat is not trying to be:
37
+
38
+
- a "one true SDK" that does everything
39
+
- an opinionated app framework
40
+
- a replacement for understanding the protocol
