Create batch api

[guidiego]

Motivation

We have a batch endpoint inside pRest (https://docs.postgres.rest/batch-operations/), but we don’t have an client method the reflect it yet.

Interface Sample

const table = cli.tableConnector<TestEntity>('prest.public.test')
table.batch(data) // or table.batch<TestEntityInput>(data)
table.batch([data]) // should work too

Approach

We need to change the behavior of Api.call to be able to receive adapt new parameters. Something like:

Feel free to think in a better approach

type RequestOpts<Input> = {
  data?: Input;
  query?: string;
}

public call<T>(method: Method, path: string, opts: RequestOpts): Promise<T> {
    const axiosFn = axios[method];
    const uri = this.baseUrl + path + opts.query;
    const dataGetter = (promise) => promise.then(({ data }) => data);

    if (['put', 'post', 'patch'].indexOf(method)) {
       return dataGetter(axiosFn(uri, opts.data));
    }

    return dataGetter(axiosFn(uri));
}

After doing that, we need to add a .batch method inside TableConnector:

public batch<Input = T>(data: Input) {
  this.call<T>('post', `/batch/${this.dbPath}`)
}
