Based on the investigation of the triggersActions plugin bundle size:

, there are three different areas (PRs) which should be changed to reduce the non required file loads:

1. change all SVG files to be lazy loaded as a React components. This will save us: 13Kb

2. remove direct exposure of Jira, IBM Resilient and ServiceNow in x-pack/plugins/triggers_actions_ui/public/common/index.ts. This is historically used by the Cases plugin and should be changed to use triggersActionsUi plugin setup contract, which has this data through the actionsTypeRegistry.

3. change action type validation methods validateConnector and validateParams to be asynchronous and load(+ memoize) translations only when it's executed. This will save us: 15Kb

4. minor code refactoring:

• change ActionForm, AlertConditions, AlertConditionsGroup to be exposed through the plugin start contract and remove direct component links from Security plugin
• move shared components props definitions to the x-pack/plugins/triggers_actions_ui/public/types.ts ;
• security plugin should use actions API call instead of direct linking to the triggersActionsUi plugin files;
• remove the usage duplication for x-pack/plugins/triggers_actions_ui/public/common/get_add_alert_flyout.tsx, x-pack/plugins/triggers_actions_ui/public/common/get_add_connector_flyout.tsx, x-pack/plugins/triggers_actions_ui/public/common/get_edit_alert_flyout.tsx, x-pack/plugins/triggers_actions_ui/public/common/get_edit_connector_flyout.tsx;
• replace <Fragment></Fragment> with shorter version <></>;
• remove not used imports from x-pack/plugins/triggers_actions_ui/public/index.ts
