Apify API client for JavaScript

This library implements a JavaScript / Node.js client for the Apify API. The main philosophy is that the library is just a thin wrapper around the API - its functions should exactly correspond to the API endpoints and have the same parameters.

The full Apify client documentation is available on a separate web page. For more complex operations with the Apify platform, see the Apify SDK.

Installation

npm install apify-client --save

Usage

const ApifyClient = require('apify-client');

// Configuration
const apifyClient = new ApifyClient({
    userId: 'jklnDMNKLekk',
    token: 'SNjkeiuoeD443lpod68dk',
});

// Storage
const store = await apifyClient.keyValueStores.getOrCreateStore({ storeName: 'my-store' });
apifyClient.setOptions({ storeId: store._id });
await apifyClient.keyValueStores.putRecord({
    key: 'foo',
    body: 'bar',
    contentType: 'text/plain',
});
const record = await apifyClient.keyValueStores.getRecord({ key: 'foo' });
const keys = await apifyClient.keyValueStores.getRecordsKeys();
await apifyClient.keyValueStores.deleteRecord({ key: 'foo' });

// Crawlers
const crawler = await apifyClient.crawlers.getCrawlerSettings({ crawlerId: 'DNjkhrkjnri' });
const execution = await apifyClient.crawlers.startExecution({ crawlerId: 'DNjkhrkjnri' });
apifyClient.setOptions({ crawlerId: 'DNjkhrkjnri' });
const execution = await apifyClient.crawlers.startExecution();

// Actors
const act = await apifyClient.acts.getAct({ actId: 'kjnjknDDNkl' });
apifyClient.setOptions({ actId: 'kjnjknDDNkl' });
const build = await apifyClient.acts.buildAct();
const run = await apifyClient.acts.runAct();

Global configuration

You can set global parameters when you are creating instance of ApifyClient:

const apifyClient = new ApifyClient({
    userId: 'jklnDMNKLekk', // Your Apify user ID
    token: 'SNjkeiuoeD443lpod68dk', // Your API token
    promise: Promise, // Promises dependency to use (default is native Promise)
    expBackOffMillis: 500, // Wait time in milliseconds before making a new request in a case of error
    expBackOffMaxRepeats: 8, // Maximum number of repeats in a case of error
});

Tp obtain your user ID and API token please visit your Apify Account page.

Promises, await, callbacks

Every method can be used as either promise or with callback. If your Node version supports await/async then you can await promise result.

const options = { crawlerId: 'DNjkhrkjnri' };

// Awaited promise
try {
    const crawler = await apifyClient.crawlers.getCrawlerSettings(options);

    // Do something crawler ...
} catch (err) {
    // Do something with error ...
}

// Promise
apifyClient.crawlers.getCrawlerSettings(options)
    .then((crawler) => {
        // Do something crawler ...
    })
    .catch((err) => {
        // Do something with error ...
    });

// Callback
apifyClient.crawlers.getCrawlerSettings(options, (err, crawler) => {
    // Do something with error and crawler ...
});

Parsing of date fields

Apify client automatically parses fields that ends with At such as modifiedAt or createdAt to Date object. This does not apply to user generated content such as:

• Crawler results
• Dataset content
• Key-value store records

Package maintenance

• npm run test to run tests
• npm run test-cov to generate test coverage
• npm run build to transform ES6/ES7 to ES5 by Babel
• npm run clean to clean build/ directory
• npm run lint to lint js using ESLint in Airbnb's Javascript style
• npm publish to run Babel, run tests and publish the package to NPM
