@architect/plugin-lambda-invoker
Interactively invoke Lambdas in Architect Sandbox with arbitrary events
Install
Into your existing Architect project:
npm i @architect/plugin-lambda-invoker --save-dev
Add the following to your Architect project manifest (usually app.arc
):
@plugins
architect/plugin-lambda-invoker
Usage
CLI
While Sandbox is running, type i
in your terminal to bring up the Lambda invocation menu. Then select the Lambda you'd like to invoke.
By default, this plugin will populate your menu with all @events
, @queues
, @scheduled
, and @tables-streams
; you can limit this menu (or expand it with additional pragmas) by adding the following setting to a pref[erence]s.arc
file:
@sandbox
invoker http scheduled # This would populate @http + @scheduled Lambdas, and ignore all others
Tip: you can navigate the invocation menu by typing numbers (zero-indexed)!
Programmatic
The plugin also passes through the Sandbox invoker for programmatic use (such as in a test environment). This method is only available after Sandbox has finished initializing.
let sandbox = require('@architect/sandbox')
let invokerPlugin = require('@architect/plugin-lambda-invoker')
await sandbox.start()
await invokerPlugin.invoke({
pragma: 'scheduled',
name: 'my-scheduled-event',
payload: { ok: true },
})
await sandbox.end()
Invocation mocks
By default, Lambdas are invoked with an empty payload ({}
); if you'd like to invoke your Lambdas with arbitrary payloads, create a file containing invocation mocks.
Invocation mock files live in your root with one of these filenames: sandbox-invoke-mocks.json
or sandbox-invoke-mocks.js
. These files should be structured like so:
Assuming this project manifest:
@events
background-task
@queues
analytics
@scheduled
backup-database
@tables-streams
tableName
If you wanted to add one or more mocks to each of the three Lambdas above, create the following sandbox-invoke-mocks.js
(or equivalent JSON) file with the format of [pragmaName][lambdaName][mockName]
:
module.exports = {
events: {
'background-task': {
'my-first-mock': { /* payload */ },
'another-mock': { /* payload */ },
}
},
queues: {
analytics: {
'one-more-mock': { /* payload */ },
'just-a-mock': { /* payload */ },
}
},
scheduled: {
'backup-database': {
'a-mock-for-this': { /* payload */ },
'the-last-mock': { /* payload */ },
}
},
'tables-streams':{
tableName:{
INSERT:{ /* payload */ },
MODIFY:{ /* payload */ },
REMOVE:{ /* payload */ },
}
}
}
Tip: when using
sandbox-invoke-mocks.js
, you can dynamically (synchronously) generate mocks on startup
