I have already made a topic that gives me information about how to open the composer with pre-filled information, besides, I got some useful answer about working with actions too, those Topics can be found at:
- [https://meta.discourse.org/t/accessing-the-createtopic-action-while-on-a-topic-route/26423/6](https://meta.discourse.org/t/accessing-the-createtopic-action-while-on-a-topic-route/26423/6)
- [Open Composer with Prefilled information](https://meta.discourse.org/t/open-composer-with-prefilled-information/82915)
However, I face the problem that the composer gets open but it doesn’t open instantly, instead, the app moves to: `/latest` URL and once the loading there finishes THEN the composer opens. In that sense, I am posting this in order to **know if there is a better way to ensure the composer opens without load a new page so it can be open instantly (as soon the user click the button)** The code I use looks like:
```
_openComposerWithParams($form) {
var serializedData = $form.serialize();
var pathToOpenComposer = `/new-topic?${serializedData}`
// open composer using query params
DiscourseURL.routeTo(`${pathToOpenComposer}`);
}
```
and of course, I have a `preventDefault` on the form submission to avoid redirections.
```
$form.on('submit', (e) => {
e.preventDefault();
this._openComposerWithParams($form);
});
```
**PD:** I am publishing all these topics around quite the same context not because I stop to make my research and wants someone does my homework but to actually helps someone else with the same problems.
Lastly, I didn’t mark this as a “BUG” cause sounds more like I am doing something wrong cause I do not think this is the expected behavior.

You could do something like this in your button’s action:
```plaintext
const { CREATE_TOPIC, DRAFT } = require('discourse/models/composer').default;
composer = Discourse. __container__.lookup('controller:composer');
composer.open({
action: CREATE_TOPIC,
draftKey: DRAFT,
title: "Pre-filled topic title!",
topicBody: "Pre-filled topic body goes here"
});
```
You can pass additional data to the composer’s `open()` method such as tags, category ID, target usernames if you’re sending a message and so on. There are a lot of clues in this file:
