# TODO app on Golem Cloud



I assume you have set up Rust's toolchain and installed `cargo-component`. If not, please refer to [Golem Cloud documentation](https://www.golem.cloud/learn/rust) for instructions.



Then upload the Wasm binary and run it on Golem Cloud (skip to step 6 if you have already set up Golem CLI):



1. Download the latest version of Golem CLI by [signing up](https://www.golem.cloud/sign-up) for the Developer Preview.

2. Unzip the bundle to a directory.

3. Define a shell alias to the Golem CLI for convenience. For example:



  ```bash

  alias golem='{path-to-directory}/golem-cli/bin/golem'

  ```



4. Run `golem account get` to go through the authorization process if you haven't done so.

5. `cd` back to our project directory.

6. Run the following command to upload the binary.



  ```bash

  golem component add --component-name todolist target/wasm32-wasi/release/todos.wasm

  ```



7. Then run this command to create an instance of our app.



  ```bash

  golem instance add --instance-name todos-inst-1 --component-name todolist

  ```



8. Define another shell alias to invoke the instance. For example:



  ```bash

  alias todos='golem instance invoke-and-await --instance-name todos-inst-1 --component-name todolist --function $*'

  ```



9. Now let's get organized! ✅



  * Run the `count-all` command to verify that our todo list is currently empty.



  ```bash

  todos golem:todos/api/count-all --parameters '[]'

  ```



  * Let's add some todo's using `add` command. We will see a payload of newly-created todo item returning from each call.



  ```bash

  todos golem:todos/api/add --parameters '[{"title": "todo #1", "priority": "low", "deadline": null}]'



  todos golem:todos/api/add --parameters '[{"title": "todo #2", "priority": "high", "deadline": "2022-06-18 13"}]'



  todos golem:todos/api/add --parameters '[{"title": "todo #3", "priority": "medium", "deadline": "2023-06-19 08"}]'

  ```



  * Now we can run the `search` command to retrieve these todo's by filtering by keyword.



  ```bash

  todos golem:todos/api/search --parameters '[{"keyword": "todo"}]'

  ```



  * `search` without any keyword will return top 10 todo's sorted by the "title" field.



  ```bash

  todos golem:todos/api/search --parameters '[{}]'

  ```



  * We can sort the search results by "priority", "status" or "deadline", as well as limiting the number of results by setting the `limit` field (100 max).



  ```bash

  todos golem:todos/api/search --parameters '[{"sort": "priority", "limit": 2}]'

  ```



  * If we know the UUID of a todo item, we can also retrieve that item by using the `get` command. For example:



  ```bash

  todos golem:todos/api/get --parameters '["90e00f90-eda0-4448-80ec-b019898d1150"]'

  ```



  * Let's check and see if there is any todo currently in progress.



  ```bash

  todos golem:todos/api/search --parameters '[{"status": "in-progress"}]'

  ```



  * We don't. Let's start working on one and update its status to in-progress.



  ```bash

  todos golem:todos/api/update --parameters '["90e00f90-eda0-4448-80ec-b019898d1150", {"status": "in-progress"}]'

  ```



  * We can delete a todo by specifying its UUID in the `delete` command.



  ```bash

  todos golem:todos/api/delete --parameters '["90e00f90-eda0-4448-80ec-b019898d1150"]'

  ```



  * We can also delete all the "done" items by running the `delete-done-items` command. This command will return the number of deleted items.



  ```bash

  todos golem:todos/api/delete-done-items --parameters '[]'

  ```



  * Finally we delete all todo's with the `delete-all` command. This command will also return the number of deleted items.



  ```bash

  todos golem:todos/api/delete-all --parameters '[]'

  ```
