HowTo Download big file

[item]

Hello,
browser security is restrictif ..
so when you have a big download .. here solution :

client/ detail

define('custom:views/periode/detail', 'views/detail', function (Dep) {

return Dep.extend({
setup: function () {
Dep.prototype.setup.call(this);
this.addMenuItem('buttons', {
name: 'rectif',
label: 'rectif',
style: 'default',
action: 'rectif'
}, true);
},

actionRectif: function () {
$.ajax({
url: 'Periode/action/rectif',
type: 'POST',
data: JSON.stringify({
id: this.model.id
}),
}).done(function (result) {
if (result['status'])
{
Espo.Ui.notify(false);
Espo.Ui.notify( result['status'] , 'success', 2000);

var byteString = atob(result.file.split(',')[1]);
var ab = new ArrayBuffer(byteString.length);
var ia = new Uint8Array(ab);

for (var i = 0; i < byteString.length; i++) {
ia[i] = byteString.charCodeAt(i);
}

window.location = URL.createObjectURL(new Blob([ab], { type: 'application/zip' }));

}else{
Espo.Ui.notify("Houston we have a problem!", 'danger', 2000);
}
}.bind(this));
},
afterRender: function () {
Dep.prototype.afterRender.call(this);
},

});
});

Just for reference, how big is big here?

Is it above the PHP size limit config? 100MB? 1GB?

Hello,
mistake... it's more this :

https://www.yaplex.com/blog/avoid-browser-pop-up-blockers

when server take time to respond to ajax call.. pop-up is blocked.
so with detail.view function, it's not blocked.
