stac-migrate

A library to update STAC files to the latest version (1.1.0 at the moment of writing). Supports updating STAC versions 0.6.0 and later.

Version of this library: 2.0.0

Usage

JavaScript / Node

Add to your project with npm install @radiantearth/stac-migrate --save

Import the library: const Migrate = require('@radiantearth/stac-migrate');

• Migrate (auto-detection): Migrate.stac(stac: object, updateVersionNumber: boolean = true) => object This method does not migrate the Commons extension - use Migrate.item if you have used the Commons extension.

• Migrate a STAC Collection: Migrate.collection(collection: object, updateVersionNumber: boolean = true) => object

• Migrate a STAC Catalog: Migrate.catalog(catalog: object, updateVersionNumber: boolean = true) => object

• Migrate a STAC Item: Migrate.item(item: object, collection: object = null, updateVersionNumber: boolean = true) => object

  The collection parameter is only required to migrate the Commons extension. Otherwise, you don't need to pass this paramater.

• Migrate a STAC CollectionCollection: Migrate.collectionCollection(apiCollections: object, updateVersionNumber: boolean = true) => object

• Migrate a STAC ItemCollection: Migrate.itemCollection(apiItems: object, updateVersionNumber: boolean = true) => object

Note: All changes will be applied in-place! If you don't want the input object to change, make a deep clone before. If you don't have a library which supports this (e.g. lodash) you can simply use var clone = JSON.parse(JSON.stringify(object));.

CLI

You can also use the CLI to migrate a single file. The commands follow the different methods above and has the same "restrictions" as above.

• Migrate (auto-detection, override): npx stac-migrate <source_path>
• Migrate (auto-detection, save to a different file with 4 spaces indentation): npx stac-migrate <source_path> --dest <dest_path> --indent 4
• Migrate a STAC Collection: npx stac-migrate <source_path> <dest_path> --collection
• Migrate a STAC Catalog: npx stac-migrate <source_path> <dest_path> --catalog
• Migrate a STAC Item: npx stac-migrate <source_path> <dest_path> --item --collection_path <collection_path>
• Migrate a STAC Item Collection: npx stac-migrate <source_path> <dest_path> --item_collection
• Migrate a STAC Collection Collection: npx stac-migrate <source_path> <dest_path> --collecions
