AWS EventBridge viewer

mnml-aws-eventbridge is a terminal browser for AWS EventBridge — list event buses or rules-per-bus, inspect event patterns / schedules / state / targets, jump to the console. Runs standalone in any terminal.

Install

cargo install --git https://github.com/chris-mclennan/mnml-aws-eventbridge --tag v0.2.0 mnml-aws-eventbridge

You’ll also need the AWS CLI on your $PATH with credentials configured.

Setup

1. Verify the AWS CLI works. aws events list-event-buses must succeed.
2. Run once to scaffold the config: mnml-aws-eventbridge.
3. Edit ~/.config/mnml-aws-eventbridge.toml — add your tabs.
4. Re-run.

Auth shape

Pure shell-out to the aws CLI — same chain as the other AWS siblings.

Config

# Optional top-level region:
# region = "us-east-1"

refresh_interval_secs = 60

[[tabs]]
name = "Buses"
kind = "buses"

[[tabs]]
name = "Default rules"
kind = "rules"
event_bus_name = "default"

[[tabs]]
name = "Orders bus"
kind = "rules"
event_bus_name = "orders-events"

Tab kinds

kind	What it shows	Required fields
buses (default)	Every event bus in the region	none
rules	Rules on event_bus_name. Use "default" for the account-wide default bus	event_bus_name

Layout

• Tab strip: one tab per [[tabs]] entry, with per-tab count badge
• Items table (left, 45%): name + state / schedule (rules) or “event bus” (buses)
• Detail panel (right, 55%): focused item’s full detail
  • Bus: name, created, last-modified, ARN, optional resource policy JSON
  • Rule: name, state, bus, schedule expression, role, managed-by, ARN, description, event pattern JSON, followed by a Targets (N) section (v0.2) — one row per target as <service> <arn-tail> with an optional input: snippet underneath. <service> is extracted from the target ARN (arn:aws:lambda:… → lambda, arn:aws:sqs:… → sqs, etc.). Display caps at 8 rows with … N more overflow when a rule fans out wider than that. Targets are fetched lazily via list-targets-by-rule keyed by <bus>::<rule> and refreshed when the cursor lands on a new rule.
• Status: active count, key hints

Keys

Chord	Action
1-9	Switch to that tab
Tab / BackTab	Cycle tabs
↑ / k, ↓ / j	Move selection
PgUp / PgDn	Jump 10 rows
g / G	Top / bottom
Enter / o	Open EventBridge console for the focused item
y	Yank focused item’s ARN to clipboard
r	Refresh active tab
q / Esc / Ctrl+C	Quit

Two run modes

Standalone

mnml-aws-eventbridge

Hosted as a mnml Pty pane

:term mnml-aws-eventbridge

Wire it into mnml’s left rail

mnml-aws-eventbridge ships as a default chip in mnml’s rail under INTEGRATIONS. Bound to <leader>i e in the whichkey leader menu (vim mode), or palette-runnable as forge.open_eventbridge.

Status

v0.2 — per-rule targets list. New backend functions list_targets_by_rule + a Target struct (Id / Arn / Input / InputPath / RoleArn). Target::service() extracts the AWS service from a target ARN (arn:aws:lambda:… → lambda). The detail panel for a focused rule now grows a Targets (N) section showing each target as <service> <arn-tail> with an optional input: snippet. Lazily fetched via App.focused_targets keyed by <bus>::<rule>, refreshed on cursor move. Caps display at 8 with … N more overflow.

v0.1 — buses list, rules-per-bus list (paginated), focused-item detail panel, console open, ARN yank.

Held back for v0.3+:

• Schedules tab (EventBridge Scheduler — separate service)
• Archives + replays tab
• Test event sender (put-events)
• Rule enable/disable toggle
• Rule state filter (ENABLED-only / DISABLED-only / managed-by-aws)
