# SMART Health Cards Validation SDK
This project provides a tool to help implementers of the [SMART Health Card Framework](https://smarthealth.cards/) validate the artefacts they produce. The package's version number, currently `0.1.1`, matches the [specification version](https://smarthealth.cards/changelog/) the tool validates.
This project provides a tool to help implementers of the [SMART Health Card Framework](https://smarthealth.cards/) validate the artefacts they produce. The package's version number, currently `0.2.0`, matches the [specification version](https://smarthealth.cards/changelog/) the tool validates.
## Setup
@ -38,7 +38,7 @@ To validate health card artefacts, use the `shc-validator.ts` script, or simply
Options:
-v, --version display specification and tool version
-p, --path <path> path of the file to validate
-p, --path <path> path of the file to validate. Can be repeated for the qr and qrnumeric types, to provide multiple file chunks
-t, --type <type> type of file to validate (choices: "fhirbundle", "jwspayload", "jws", "healthcard", "qrnumeric", "qr", "jwkset")
-l, --loglevel <loglevel> set the minimum log level (choices: "debug", "info", "warning", "error", "fatal", default: "warning")
-o, --logout <path> output path for log (if not specified log will be printed on console)
@ -53,6 +53,10 @@ To validate a `QR.png` file, call:
node . --path QR.png --type qr
Multiple `path` options can be provided for QR artefacts (`qrnumeric` and `qr` types) split in multiple files , one for each chunk. For example, to validate a numeric QR code split in three chunks `QR1.txt`, `QR2.txt`, `QR3.txt`, call:
node . --path QR1.txt --path QR2.txt --path QR3.txt --type qrnumeric
The supported file types, as expressed with the `--type` option, are:
- *fhirbundle*: a JSON-encoded FHIR bundle
- *jwspayload*: a JSON Web Signature (JWS) payload, encoding a health card
