JSON File Content Generation Guide
Preview JSON files via frago view with automatic formatting and syntax highlighting.
Preview Commands
frago view data.json # Default theme
frago view config.json --theme monokai # Specify theme
Rendering Features
Automatic Formatting
- JSON content automatically beautified (Pretty Print)
- Indentation aligned
- Key-value pairs clearly displayed
Syntax Highlighting
| Element | Color Example (github-dark) |
|---|---|
| Key names | Purple #d2a8ff |
| String values | Blue #a5d6ff |
| Numbers | Cyan #79c0ff |
| Booleans | Red #ff7b72 |
| null | Red #ff7b72 |
| Brackets/commas | White #c9d1d9 |
JSON Format Specification
Correct Format
{
"name": "Project Name",
"version": "1.0.0",
"enabled": true,
"count": 42,
"tags": ["tag1", "tag2"],
"config": {
"nested": "value"
},
"nullable": null
}
Common Errors
| Error | Example | Fix |
|---|---|---|
| Trailing comma | {"a": 1,} | {"a": 1} |
| Single quotes | {'a': 1} | {"a": 1} |
| Unquoted keys | {a: 1} | {"a": 1} |
| Comments | // comment | Comments not supported |
| undefined | undefined | Use null |
Best Practices
1. Indentation
- Use 2 or 4 spaces for indentation
- Maintain consistency
2. Key Naming
- Use snake_case or camelCase
- Maintain consistency throughout the file
{
"user_name": "snake_case style",
"userName": "camelCase style"
}
3. Data Organization
- Group related fields
- Place important fields first
{
"id": "001",
"name": "Important fields first",
"metadata": {
"created_at": "2024-01-01",
"updated_at": "2024-01-02"
}
}
4. File Size
- Single file < 1MB optimal
- Consider pagination or splitting files for large data
Use Cases
- API response data preview
- Configuration file viewing
- Data structure review
- Debug data inspection
Display Themes
Same as code files, supports the following themes:
| Theme | Command |
|---|---|
| github-dark (default) | frago view data.json |
| monokai | frago view data.json --theme monokai |
| atom-one-dark | frago view data.json --theme atom-one-dark |
Notes
| Issue | Cause | Solution |
|---|---|---|
| Parse failure | JSON format error | Use JSON validator |
| Truncated display | Value too long | Use nested structure |
| Slow rendering | File too large | Split or simplify |
JSON Validation
Ensure JSON is valid before preview:
# Python validation
python -m json.tool data.json
# jq validation
jq . data.json
Related Tools
- jq: Command-line JSON processor
- jsonlint: JSON validator
- VSCode: JSON editing and formatting
