示例1: it
it('should cache value for next subscription and not call callbackFunc again', () => {
let calls = 0;
function callback(datum: number, cb: (err: any, n: number) => void) {
calls++;
cb(null, datum);
}
const boundCallback = bindNodeCallback(callback, rxTestScheduler);
const results1: Array<number | string> = [];
const results2: Array<number | string> = [];
const source = boundCallback(42);
source.subscribe(x => {
results1.push(x);
}, null, () => {
results1.push('done');
});
source.subscribe(x => {
results2.push(x);
}, null, () => {
results2.push('done');
});
rxTestScheduler.flush();
expect(calls).to.equal(1);
expect(results1).to.deep.equal([42, 'done']);
expect(results2).to.deep.equal([42, 'done']);
});示例2: mergeMap
const compileScssFile = mergeMap((file: WorkFile) => {
const compileSass$: any = bindNodeCallback(renderSass);
return compileSass$({file: file.src}).pipe(
mergeMap((res: Result) => processCss(res.css)),
mergeMap((result: any) => createCssFile(file.distCss, result.css)),
tap(() => logSuccess(file))
);
});示例3: function
constructorZone.run(() => {
func = function(arg: any, callback: (error: any, result: any) => any) {
expect(Zone.current.name).toEqual(constructorZone.name);
callback(null, arg);
};
boundFunc = bindNodeCallback(func);
observable = boundFunc('test');
});
