This project is still being developed

• Easy override, you need only override Connection and QueryBuilder.
• Support cache

Example for LibrariesIO:

class QueryBuilder extends BaseQueryBuilder {

    public function buildAuth(Request $request, $params = array()) {
        if ($this->db->apiKey) {
            $request->addData([
                'api_key' => $this->db->apiKey,
            ]);
        }
        return parent::buildAuth($request, $params);
    }

    public function buildMethod(Request $request, $action, $params = array()) {
        return $request->setMethod('GET');
    }

    public function buildFrom(Request $request, $from, $params = []) {
        if ($from === 'project') {
            $from = 'search';
        } else {
            $from .= 's';
        }

        return parent::buildFrom($request, $from, $params);
    }

    public function buildCount(Request $request, $count, $params = []) {
        if ($count) {
            $request->setMethod('HEAD');
            $request->addData(['per_page' => 1]);
            $request->on(Request::EVENT_AFTER_SEND, function (RequestEvent $event) {
                $count = $event->response->headers->get('total', 0);
                $event->response->setData((int) $count);
            });
        }

        return $request;
    }

    public function buildOrderBy(Request $request, $orderBy, $params = array()) {
        if (empty($orderBy)) {
            return $request;
        }

        foreach ($orderBy as $name => $direction) {
            $request->addData([
                'sort'  => $name,
                'order' => $direction === SORT_DESC ? 'desc' : 'asc',
            ]);
            break;
        }

        return $request;
    }

    public function buildLimit(Request $request, $limit, $offset = 0, $params = []) {
        if ($limit && $limit > 0) {
            $request->addData([
                'per_page' => $limit,
            ]);

            if ($offset && $offset > 0) {
                $request->addData([
                    'page' => 1 + $offset / $limit,
                ]);
            }
        }
        return $request;
    }

}

Have you seen yii2-hiart-httpclient? It is mentioned in README.

[edgardmessias]

Yes, I saw.

My change tries to work better with Request and Response simplifying override.

[hiqsol]

These are huge changes. Not really compatible... And we are using hiart in production!
Need time to look closer.
@SilverFire, @tafid please take a look too.

[hiqsol]

First look:

• I'm not sure about the main change, I know we're doubling a lot from yii2-httpclient but I need more time to consider and evaluate
• we need Collection, it must be returned back
• abstract query builder must be returned back, definitely not all apis are REST, our is not
• also API can be non HTTP based, eg SOAP. Is yii2-httpclient compatible this way?

Such huge PR is really difficult to work with...

Let's summarize​ changes:

• rewrite with yii2-httpclient
• refactored Query builder
• added caching

Please continue what I missed.
