Yield promises in generator functions
npm i -s yieldpromiseconst run = require("yieldpromise");
const fetch = require("node-fetch");
// Using as a standalone function
run(function* main() {
const a = yield fetch("https://jsonplaceholder.typicode.com/posts/1");
const b = yield a.json();
console.log(b);
});Since run injects resolve and reject as parameters to the child generator function, it can be used inside promise chain
const run = require("yieldpromise");
const fetch = require("node-fetch");
run(function* main(resolve, reject) {
const a = yield fetch("https://jsonplaceholder.typicode.com/posts/1");
const b = yield a.json();
resolve(b);
})
.then(x => x.userId)
.then(console.log);const run = require("yieldpromise");
const fetch = require("node-fetch");
fetch("https://jsonplaceholder.typicode.com/posts/1")
.then(x =>
run(function* main(resolve, reject) {
const a = yield x.json();
const b = a.userId;
resolve(b);
})
)
.then(console.log);
