@qualifyze/airtable

What is @qualifyze/airtable?

A more powerful JS/TS client for the Airtable API that can be used with Airtable's API directly or through proxy-endpoints that provide a different Auth mechanism.

Why is @qualifyze/airtable useful?

In comparison to the official client, @qualifyze/airtable brings these advantages:

• You can use this client to connect multiple API endpoints.
• You can use this client to connect to Airtable API endpoints with an alternative auth-mechanism.
• Allows type-annotations and run-time validations for table-fields.
• Pagination when listing records is much easier through Async Iterators.
• Allows the use of Array Notation when filtering queries through @qualifyze/airtable-formulator.

How to use it?

The API of this client for the most part is identical to the official clients API.

Connect to the official API using the official client

import Airtable from "airtable";
import { Base } from "@qualifyze/airtable";

Airtable.configure({ apiKey: "YOUR_SECRET_API_KEY" });
const officialClient = new Airtable();

const base = Base.fromOfficialClient(officialClient, myBaseId);

Use Type Annotation for table fields

type Person = {
  name?: string;
  age?: number;
};

const persons = base.table<Person>("persons");

const record = persons.create({
  name: "Eve",
  age: "not a number", // Type Error
});

Add run-time validators

With the Validator interface you can wrap any validation library to validate your data at runtime.

import { Validator } from "./validator";

const validator: Validator<Person> = {
  createValidator(reference?: string) {
    return {
      isValid(data: unknown): data is Person {
        // Return true if data is a person.
      },
      getValidationError(): Error | null {
        // Return validation errors that were encountered in the last call to isValid().
        // Include reference to easily identify the invalid record.
      },
    };
  },
};

const persons = base.table("persons", validator);

Iterating over list results

const query = {
  filterByFormula: [">", { field: "age" }, 35],
};

for await (const person of persons.select(query)) {
  console.log(person.data);
}

As with any Async iterators it has to be warned that an iterator can only be used once at a time:

async function runIteration(query) {
    for await(const record of query) {
        // Do something.
    }
}

// BAD: Use same same query in parallel iterators.
const query = table.query({});
Promise.all(runIteration(query), runIteration(query)); // <- BAD

// GOOD: For parallel iterations use separate query obejcts.
const queryA = table.query({});
const queryB = table.query({});
Promise.all(runIteration(queryA), runIteration(queryB)); // <- GOOD

Use an alternative Authentication Method, rather than the official client

import { Base, Endpoint, ActionPayload, RestMethod } from "@qualifyze/airtable";

const myClient: Endpoint = {
  async runAction(
    method: RestMethod,
    { path, payload: { query, body } }: ActionPayload
  ): Promise<unknown> {
    // Implement your own Endpoint interface that
    // Throw any API-level errors.
    // Return the response payload as is.
  },
};

const base = new Base(myClient);

Key API incompatibilities to the official client

No Callback APIs

It's 2022. Why would you need callback APIs?

Use Promises or async/await.

Record objects are Immutable:

So it won't drive you insane.

const record = persons.find("my-id");
const updatedRecord = await record.update({ age: record.data.age + 1 });

console.log({
  before: record.data.age,
  after: updatedRecord.data.age
});

There are no .set() or .get() methods on the Record API.

Testing changes

In addition to usual lint and test scripts, there is an integration test to check the client against the real airtable base.

• create the file .env based on .env.example
• pick a table with at least two string fields where it's ok to create new records
• bash npm run integration

All the created records are deleted in case of the successful execution.

Contributing code

Add the changeset description using the interactive command npx changeset. This will create a new file in .changeset folder which defines how the change should affect the package version (major, minor, patch) and contains a small description for the release notes. The file should be part of the same pull requests it describes.

Release a new version

Each PR with changeset files merged into the main branch will open/update PR to release the package with the proper version. Merging that PR will bump the version, create a GitHub release and publish the new version to the npm registry.

Unfortunately, the test workflow required to merge a PR is not triggered by the version PR. The workaround is assigning PR to yourself which is added as an additional trigger for the test workflow.
