ValidJSON
Severity: error | Type: JSON | Aliases: ValidJson
This check exists to prevent invalid JSON files in your platformOS application. It validates that all .json files in your project contain well-formed JSON. When a JSON schema is available for a particular file, the check also validates the content against that schema.
Examples
✗ Incorrect Code Example (Avoid using this):
{
"name": "My App",
"version": 1,
"tags": ["liquid", "platformos",]
}
The trailing comma in the array is invalid JSON.
{
name: "My App"
}
Property names must be quoted strings in JSON.
✓ Correct Code Example (Use this instead):
{
"name": "My App",
"version": 1,
"tags": ["liquid", "platformos"]
}
