## Commands
18
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 typescript definitions of the lexicons for inference and later: validation
46
-
47
19
### `gen-emit`
48
20
49
21
Emit JSON lexicon schemas from authored TypeScript files.
···
78
50
79
51
1. **Author lexicons in TypeScript** using the `prototypey` library
80
52
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
53
83
54
```bash
84
55
# Write your lexicons in TypeScript
···
86
57
87
58
# Emit JSON schemas
88
59
prototypey gen-emit ./schemas ./src/lexicons/**/*.ts
89
-
90
-
# Generate TypeScript types from schemas
91
-
prototypey gen-inferred ./generated ./schemas/**/*.json
92
60
```

The `prototypey` package includes a CLI with two main commands:
66
66
67
-
#### `gen-inferred` - Generate TypeScript from JSON schemas
68
-
69
-
```bash
70
-
prototypey gen-inferred <outdir> <schemas...>
71
-
```
72
-
73
-
Reads ATProto lexicon JSON schemas and generates TypeScript types.
74
-
75
-
**Example:**
76
-
77
-
```bash
78
-
prototypey gen-inferred ./generated/inferred ./lexicons/**/*.json
79
-
```
80
-
81
67
#### `gen-emit` - Emit JSON schemas from TypeScript
82
68
83
69
```bash
