Kaws

Named after the artist, kaws is a backend service that powers artsy.net collection pages. What are collections you ask? A Collection is a prefiltered version of Artsy's Collect page for marketing purposes.

Prerequisites

node.js 8.12.0 or newer
yarn 1.10.1 or newer
MongoDB 4.x

Note on Google API Access

KAWS exposes a yarn import-collections command that re-imports collection data from a specified Google spreadsheet. Invoke it like:

hokusai production run "yarn import-collections SPREADSHEET_ID SHEET_NAME"

...where SPREADSHEET_ID is from the Google spreadsheet's URL and SHEET_NAME is the name of the selected sheet. The ID must match the configured SPREADSHEET_IDS_ALLOWLIST list, and the following Google credentials are required:

GOOGLE_API_KEY
GOOGLE_CLIENT_ID
GOOGLE_CLIENT_SECRET

See the hokusai and/or the Kaws Credentials secure note in 1passsword for current values of these.

If it becomes necessary to re-generate these credentials in staging and production — as has happened a couple of times in the past — you can follow these instructions.

For local development, you can run yarn test-google-config to see if your local .env file's values for GOOGLE_CLIENT_ID, GOOGLE_CLIENT_SECRET and SPREADSHEET_IDS_ALLOWLIST validate.

Getting started

First, make sure to install dependencies:

yarn

We use the .env file to load environment-specific variables. Copy .env.example to .env so dotenv will automatically load them upon app boot:

cp .env.example .env

Usually you do not have to change them, but if you need, update the variables to match your local development setup.

Once this is done, the next step would be to load some data.

Collections data can be pulled from the live staging or production environment using the following yarn command:

yarn pull-database staging # or production

Finally, start the server by running the command below:

yarn dev
# or
hokusai dev start

Then open http://localhost:4000/playground and you should see Apollo's GraphQL Playground. Try running the GraphQL query below, and if you see real collections data coming back from the database you are good to go!

query {
  collections {
    id
    slug
    title
  }
}

Testing

yarn jest
# or
hokusai test

Did you change the GraphQL schema?

Metaphysics is the current consumer of Kaws GraphQL schema, and keeps a copy of its latest schema in https://github.com/artsy/metaphysics/tree/main/src/data. If you have made changes to the Kaws GraphQL schema, make sure you also update the copy of this schema in Metaphysics. In order to do so follow these steps:

In kaws run

yarn dump-schema

copy the _schema.graphql file generated ☝🏼 to kaws.graphql

cp _schema.graphql kaws.graphql

move the file above to your local Metaphysics under src/data and make a PR to Metaphysics with this change.

Updating the sitemap for Collect

When we update the production database with the update-database command, we also need to inform Google of the updates so newly added collections will be crawled. This could be done with the update-sitemap command. This comamnd needs to be run in the k8s container as it neeeds to point to the production databse:

hokusai production run 'yarn update-sitemap'
