These examples show how to:
Require the DataSift library - choose one of these:
var DataSift = require('datasift'); // When running from NPM package
var DataSift = require('../lib/datasift'); // When running within datasift-node repository
Create a DataSift client object - insert your API credentials:
var ds = new DataSift('YOUR_USERNAME', 'YOUR_APIKEY');
A variable to store the list ID for use later:
var listId;
This method creates a dynamic list, then shows all lists you have:
function create() {
ds.list.create({
"type": "integer",
"name": "Example integer list"
},function(err, response) {
if(err)
console.log(err);
else
{
listId = response.id;
console.log("Created list: " + response.id);
get();
}
});
}
This method shows all lists you have, then adds items to a list:
function get() {
ds.list.get(function(err, response) {
if(err)
console.log(err);
else {
console.log("Current lists: " + JSON.stringify(response));
add();
}
});
}
This method adds items to the created list, then removes some items:
function add() {
ds.list.add({
"id": listId,
"items": JSON.stringify([1,2,3,4,5])
},function(err,response) {
if(err)
console.log(err);
else {
console.log("Items have been added to the list.");
remove();
}
});
}
This method removes items from the list, then checks for item existence:
function remove() {
ds.list.remove({
"id": listId,
"items": JSON.stringify([1,2])
},function(err,response) {
if(err)
console.log(err);
else {
console.log("Items have been removed from the list.");
exists();
}
});
}
This method checks for item existence in the list, then starts a bulk replace:
function exists() {
ds.list.exists({
"id": listId,
"items": JSON.stringify([3,4])
},function(err,response) {
if(err)
console.log(err);
else {
console.log("Exists result: " + JSON.stringify(response));
replaceStart();
}
});
}
This method starts a bulk replace, then performs the replace:
function replaceStart() {
ds.list.replace.start({
"list_id": listId
},function(err,response) {
if(err)
console.log(err);
else {
console.log("Replace started");
replaceAdd(response.id);
}
});
}
This method adds items during the bulk replace, then commits:
function replaceAdd(replaceId) {
ds.list.replace.add({
"id": replaceId,
"items": JSON.stringify([1,2,3,4,5,6,7,8,9])
},function(err,response) {
if(err)
console.log(err);
else {
console.log("Replace completed");
replaceCommit(replaceId);
}
});
}
This method commits the bulk replace, then deletes the list for cleanup:
function replaceCommit(replaceId) {
ds.list.replace.commit({
"id": replaceId
},function(err,response) {
if(err)
console.log(err);
else {
console.log("Replace committed");
deleteList();
}
});
}
This method deletes the list
function deleteList() {
ds.list.delete({
"id": listId
},function(err,response) {
if(err)
console.log(err);
else {
console.log("List deleted");
}
});
}
Finally we start the process creating a list. This will lead to:
create();
