Interfacer demo-data injection

Demo-data generator aligned with the current ../interfacer-gui data model. All supported entry points delegate to init-data-sdk.mjs and use @dyne/interfacer-client; there is no duplicate raw GraphQL/REST implementation.

Generated data

Entity	Count	Details
Users	3	Designer, maker, reviewer
Machines	4	Typed and searchable machine resources
Designs	5	CAD URL, complexity, BOM, machines, materials, power requirements
Services	3	Service-type and availability filter tags
Products	5	Linked design, location, price, availability, catalog filter tags
DPPs	15	Three active passports per product
Feedback	7	Reviews and comments created through the SDK feedback client

The generated metadata and classification tags follow the current GUI creation flow:

• user tags use tag-*;
• product and service filters are generated with client.tagging;
• complexity, machine, material, license, power, and manufacturability use the SDK tag prefixes;
• image URLs, CAD URLs, licenses, declarations, price, availability, and linked designs use the shapes read by the current GUI;
• design and DPP citations share the product creation process, preserving ValueFlows traceability;
• locations are created once and passed to createProject via locationId.

Requirements

• Node.js 24 (the same version as ../interfacer-gui/.mise.toml)
• pnpm 9.13.1
• reachable Zenflows, DPP, feedback, location, and Picsum services
• ../interfacer-gui/.env.local or ../interfacer-gui/.env

The script loads .env, then applies .env.local overrides. Variables already present in the shell have the highest precedence. In particular it consumes the GUI's BASE_URL, NEXT_PUBLIC_ZENFLOWS_URL, NEXT_PUBLIC_DPP_URL, NEXT_PUBLIC_FEEDBACK_URL, location endpoint, admin token, and optional specification IDs.

An optional MODEL_URL can override the public STL URL used for designs.

Install and run

corepack enable
pnpm install
pnpm start

main.mjs is retained as a compatibility shim, so this also works:

node main.mjs

For Jupyter, install an ijavascript kernel and run interfacer_init_data.ipynb; the notebook imports the same SDK script rather than maintaining a separate injector.

InMachines catalog injector

init-data-inmachines.mjs creates a dedicated InMachines account and imports the catalog scraped from:

• https://www.inmachines.net/open-lab-starter-kit
• https://www.inmachines.net/services8f05a8a7
• the four service detail pages linked from the services page;
• the eight linked repositories in the Open-Lab-Starter-Kit GitHub organization.

The normalized, reviewable snapshot is stored in data/inmachines.json. It contains source URLs, repository and license information, descriptions, original images, BOM links, and available STEP model links.

The injector creates:

• one InMachines account, if it does not already exist;
• eight OLSK designs;
• eight InMachines-built products, each linked to its design through the same creation process;
• three DPPs per product (24 total), also cited by the product creation process;
• four services;
• one shared InMachines location in Schwarzenbek.

Validate the dataset without accessing the backend:

pnpm dry-run:inmachines

Run the complete import:

pnpm start:inmachines

To backfill only the DPPs for products already listed in results-inmachines.json, without duplicating designs, products, services, or locations:

pnpm start:inmachines:dpps

The DPP backfill checkpoints results-inmachines.json after every successful passport and skips already recorded product/index pairs when resumed.

The default identity is InMachines <info@inmachines.net>. It can be overridden with INMACHINES_NAME, INMACHINES_USERNAME, and INMACHINES_EMAIL. The deterministic demo credentials can be overridden with INMACHINES_CHALLENGE_1 through INMACHINES_CHALLENGE_5. If the email already belongs to an account created with different credentials, the script stops rather than impersonating or overwriting it.

The run writes public IDs to results-inmachines.json; private keys are never persisted there.

Output

A successful run writes results-sdk.json with created IDs and public user data. Private keys are used only in memory and are not written to the output.

The injector is additive. Re-running it reuses deterministic demo identities but creates additional resources, DPPs, and feedback where accepted by the services.
