# `Soundcheck.Check.Warning.InvalidSendUpdate`
[🔗](https://github.com/leonqadirie/soundcheck/blob/v0.1.0/lib/soundcheck/check/warning/invalid_send_update.ex#L1)

## Basics

> #### This check is disabled by default. {: .neutral}

This check has a base priority of `high` and works with any version of Elixir.

## Explanation

Flags `send_update/2,3` and `send_update_after/3,4` calls that cannot
reach a LiveComponent: the assigns name a module but carry no `:id`,
which raises `ArgumentError`, or the module is a LiveView or a plain
module. No rendered component matches such a module, so LiveView
drops the update with only a debug log, or raises when the module
does not exist.

Before:

    send_update(MyAppWeb.PostLive.Index, id: "post-form", post: post)

After:

    send_update(MyAppWeb.PostLive.FormComponent, id: "post-form", post: post)

The module must be a literal alias or `__MODULE__`, expanded as the
calling module expands it, and the `:id` check needs literal assigns
(a keyword list or map). Calls targeting `@myself` or another CID are
skipped.

Confidence: high. Tier: semantic for the module check (run `mix compile` before `mix credo`); the `:id` check works without compiling.

## Check-Specific Parameters

Use the following parameters to configure this check:

### `:excluded_paths`

  Paths to skip (atoms, binaries as path segments, or regexes).

*This parameter defaults to* `[~r/\/test\//, "test"]`.

### `:strict`

  Unused.

*This parameter defaults to* `false`.

## General Parameters

Like with all checks, [general params](`e:credo:check_params.html`) can be applied.

Parameters can be configured via the [`.credo.exs` config file](`e:credo:config_file.html`).
