# @prototypey/cli
2
+
3
+
CLI tool for generating types from ATProto lexicon schemas.
4
+
5
+
## Installation
6
+
7
+
```bash
8
+
npm install -g @prototypey/cli
9
+
```
10
+
11
+
Or use directly with npx:
12
+
13
+
```bash
14
+
npx @prototypey/cli
15

```

## Commands
18
+
19
+
### `gen-inferred`
20
+
21
+
Generate type-inferred TypeScript code from JSON lexicon schemas.
22
+
23
+
**Usage:**
24
+
25
+
```bash
26
+
prototypey gen-inferred <outdir> <schemas...>
27
+
```
28
+
29
+
**Arguments:**
30
+
31
+
- `outdir` - Output directory for generated TypeScript files
32
+
- `schemas...` - One or more glob patterns matching lexicon JSON schema files
33
+
34
+
**Example:**
35
+
36
+
```bash
37
+
prototypey gen-inferred ./generated/inferred ./lexicons/**/*.json
38
+
```
39
+
40
+
**What it does:**
41
+
42
+
- Reads ATProto lexicon JSON schemas
43
+
- Generates TypeScript types that match the schema structure
44
+
- Organizes output files by namespace (e.g., `app.bsky.feed.post` → `app/bsky/feed/post.ts`)
45
+
- Provides type-safe interfaces for working with lexicon data
46
+
47
+
### `gen-emit`
48
+
49
+
Emit JSON lexicon schemas from authored TypeScript files.
50
+
51
+
**Usage:**
52
+
53
+
```bash
54
+
prototypey gen-emit <outdir> <sources...>
55
+
```
56
+
57
+
**Arguments:**
58
+
59
+
- `outdir` - Output directory for emitted JSON schema files
60
+
- `sources...` - One or more glob patterns matching TypeScript source files
61
+
62
+
**Example:**
63
+
64
+
```bash
65
+
prototypey gen-emit ./lexicons ./src/lexicons/**/*.ts
66
+
```
67
+
68
+
**What it does:**
69
+
70
+
- Scans TypeScript files for exported lexicon namespace definitions
71
+
- Extracts the `.json` property from each namespace
72
+
- Emits properly formatted JSON lexicon schema files
73
+
- Names output files by lexicon ID (e.g., `app.bsky.feed.post.json`)
74
+
75
+
## Workflow
76
+
77
+
The typical workflow combines both commands for bidirectional type safety:
78
+
79
+
1. **Author lexicons in TypeScript** using the `prototypey` library
80
+
2. **Emit to JSON** with `gen-emit` for runtime validation and API contracts
81
+
3. **Generate inferred types** with `gen-inferred` for consuming code
82
+
83
+
```bash
84
+
# Write your lexicons in TypeScript
85
+
# src/lexicons/app.bsky.actor.profile.ts
86
+
87
+
# Emit JSON schemas
88
+
prototypey gen-emit ./schemas ./src/lexicons/**/*.ts
89
+
90
+
# Generate TypeScript types from schemas
91
+
prototypey gen-inferred ./generated ./schemas/**/*.json
92
+
```
93
+
