I'm performing multiple task and each task is dependent on previous task execution. So in my example what I want is after getting all the Id, i should get their respective blob value and then finish the execution by storing it in a variable. I'm very new to javascript and angular, please help me out. Here's what I'm trying
//this method will get the response from the rest api
async getIDFromAssets(){
this.blobDataArray=[];
this.service.getAssetsData().subscribe(async (res: JSON) => {
//after getting the response I'm filtering through it to get sepcific Id using this.getFileId() method
this.getFileId(res).then((data)=>{
console.log("blob "+data)
})
})
}
//below method will get one Id at a time and will call another method to get it's blob value
async getFileId(res){
this.fileId = [];
Object.keys(res).forEach(keys => {
if (keys == 'emb') {
let responseValue = res[keys];
Object.keys(responseValue).forEach(async (keys1) => {
if (keys1 === 'file') {
let responseArray = responseValue[keys1];
for (let file of responseArray) {
let temp: string = file.metadata.contentType;
if (temp.startsWith('image')) {
//Here I'm getting id value 'file._id' and using that I'm calling another method 'getBlobData()' to get its blob value
let data=await this.getBlobData(file._id);
this.blobDataArray.push(data);
}
}
return this.blobDataArray
}
});
}
});
}
// method to get the blob value
async getBlobData(fileId){
this.articleDetailService.getBlobDataFromAssets(fileId).subscribe(async (res)=>{
let imageObj={
'id':fileId,
'blob':res
}
return imageObj;
})
}
