Ignixa.Validation.Cli 0.0.87

FHIR Validation CLI

A command-line tool for validating FHIR resources using the Ignixa.Validation library.

Installation

Install as a .NET global tool:

dotnet tool install --global Ignixa.Validation.Cli

Or install locally in a project:

dotnet tool install Ignixa.Validation.Cli

Usage

All commands start with a FHIR version:

ignixa-validator <version> [options]

Available FHIR versions: stu3, r4, r4b, r5, r6

Validation Options

The tool supports three different usage modes:

1. Validate a JSON file and save results

Validate a FHIR resource from a file and save the validation results (as an OperationOutcome resource):

ignixa-validator r4 --input patient.json --out validation-results.json

2. Validate a JSON string

Validate a FHIR resource from a JSON string (useful for CI/CD pipelines):

Bash/Linux/macOS:

ignixa-validator r4 --json '{"resourceType":"Patient","id":"example"}' --console

PowerShell:

# Use here-string for complex JSON
ignixa-validator r4 --json '{"resourceType":"Patient","id":"example"}' --console

# Or escape quotes
ignixa-validator r4 --json '{\"resourceType\":\"Patient\",\"id\":\"example\"}' --console

Note: When using PowerShell, storing JSON in a variable can cause quoting issues. Use the JSON directly in the command or escape inner quotes properly.

3. Display formatted results in console

Validate and display nicely formatted results in the console:

ignixa-validator r4 --input patient.json --console

You can also combine --out and --console to get both file output and console display:

ignixa-validator r4 --input patient.json --out results.json --console

Output Formats

OperationOutcome (JSON file)

When using --out, the tool generates a FHIR OperationOutcome resource containing all validation issues. This format is compatible with FHIR servers and can be processed programmatically.

Console Output

When using --console, the tool displays a formatted summary similar to validator.fhir.org:

═══════════════════════════════════════════════════════════════
  FHIR Validation Results (R4)
═══════════════════════════════════════════════════════════════
  Resource Type: Patient
  Status: ✗ INVALID
═══════════════════════════════════════════════════════════════

Examples

# Validate an R4 Patient resource with console output
ignixa-validator r4 --input patient.json --console

# Validate and save OperationOutcome to file
ignixa-validator r4 --input observation.json --out validation.json

# Validate a JSON string (bash)
ignixa-validator r4 --json '{"resourceType":"Patient","id":"test"}' --console

# Validate using different FHIR versions
ignixa-validator stu3 --input patient-stu3.json --console
ignixa-validator r5 --input patient-r5.json --console

# Both file and console output
ignixa-validator r4 --input bundle.json --out results.json --console

Exit Codes

• 0 - Validation successful (no errors)
• 1 - Validation failed (errors found) or tool error
