The below code is currently working but only brining back the first parameters JSON response.
I would like to be able to call this external API a few times with different parameters and combine the responses back in one concatenated JSON response.
I have two sets of parameters that I'm using in this code but I will really would have more like 200 ideally. Any help is appreciated.
const SerpApi = require('google-search-results-nodejs');
const search = new SerpApi.GoogleSearch("674d023b72e91fcdf3da14c730387dcbdb611f548e094bfeab2fff5bd86493fe");
const handlePictures = async (req, res) => {
const params1 = {
q: "kevin durant",
tbm: "isch",
};
const params2 = {
q: "lou williams",
tbm: "isch",
};
return new Promise((rs, rj) => {
const callback1 = function(data) {
// console.log(data);
// res.send(data);
rs(data);
};
// Show result as JSON
search.json(params1 , callback1);
// how do I get this to work too? ----> search.json(params2, callback1);
// res.end();
})
};
module.exports = {handlePictures};
You can wait for multiple asynchronous jobs to complete using Promise.all. Let's say you have an array of request parameters:
const reqs = [
{ q: 'request one', tbm: 'isch' },
{ q: 'request two', tbm: 'isch' },
{ q: 'request three', tbm: 'isch' },
]
Then you could use [].map and Promise.all, and return that promise in your function.
const handlePictures = (req, res) => {
const reqs = [
{ q: 'request one', tbm: 'isch' },
{ q: 'request two', tbm: 'isch' },
{ q: 'request three', tbm: 'isch' },
];
// unfortunately the library you're using has no error handling
const promises = reqs.map(data => new Promise(resolve => {
search.json(data, resolve);
}))
// this promise resolves when all given promises are resolved
return Promise.all(promises);
};
