Question 1

How to validate JSON against a schema with jsonlint?

Accepted Answer

Use the -V option with a schema file, e.g., 'jsonlint -V schema.json data.json'. Note that it defaults to JSON Schema draft-03, so check compatibility with your schema version.

Question 2

jsonlint vs JSON.parse: which one should I use?

Accepted Answer

Use JSON.parse for basic parsing in JavaScript; jsonlint is better for detailed error reporting, formatting, and schema validation in CLI or Node.js workflows where extra features are needed.

Question 3

How to pretty print JSON files with custom indentation using jsonlint?

Accepted Answer

Use the -t option followed by the indentation character, e.g., 'jsonlint -t "  " file.json' for two spaces. This allows flexible formatting to match your project's style guide.

Question 4

Does jsonlint support JSON Schema draft 07?

Accepted Answer

No, by default it uses JSON Schema draft-03. The -e option lets you specify the environment, but support for newer drafts like draft-07 is not explicitly mentioned and likely limited.

Question 5

How to integrate jsonlint into a CI/CD pipeline?

Accepted Answer

Install jsonlint via npm in your build environment and add a step to run it on JSON files, e.g., 'jsonlint config.json'. This can fail the pipeline on invalid JSON, ensuring data correctness.

Question 6

jsonlint or jq for JSON processing?

Accepted Answer

jq is superior for querying and transforming JSON data, while jsonlint focuses on validation and formatting. Choose jq for complex manipulations and jsonlint for strict validation and readability improvements.

Question 7

Can I use jsonlint in a browser?

Accepted Answer

While it's pure JavaScript, it's designed for Node.js and may not be optimized for browsers. For browser-based validation, consider libraries like AJV for schema validation or stick with JSON.parse for simplicity.
