cljs-lambda.context
Representation & manipulation of Lambda-handler execution context.
Contexts are represented as records with keys:
:aws-request-id:client-context:log-group-name:log-stream-name:function-name:function-arn:identity(optional):handler-callback(optional)

waits?cljs
(waits? this)By default, the callback will wait until the Node.js runtime event loop is empty before freezing the process and returning the results to the caller. You can set this property to false to request AWS Lambda to freeze the process soon after the callback is called, even if there are events in the event loop.

-done!cljs
(-done! this err result)See done!
See [[done!]]
environmentcljs
(environment this)Retrieve a map of environment variables.
Retrieve a map of environment variables.
done!cljs
(done! ctx & [err result])Terminate execution of the handler associated w/ the given context, conveying the given error (if non-nil), or the given success result (if non-nil). No arguments communicates generic success.
(deflambda quick [_ ctx]
(ctx/done! ctx))
Terminate execution of the handler associated w/ the given context, conveying the given error (if non-nil), or the given success result (if non-nil). No arguments communicates generic success. ```clojure (deflambda quick [_ ctx] (ctx/done! ctx)) ```
envcljs
(env ctx k)Retrieve an environment variable by name, defaulting to nil if not found.
(env ctx "USER")
(env ctx :USER)
(env ctx 'USER)
Retrieve an environment variable by name, defaulting to `nil` if not found. ```clojure (env ctx "USER") (env ctx :USER) (env ctx 'USER) ```
fail!cljs
(fail! ctx & [err])Trivial wrapper around done!
Terminate execution of the handler associated w/ the given context, conveying the given error, if non-nil - otherwise mark the execution as failed w/ no specific error.
(deflambda purchase [item-name ctx]
(ctx/fail! ctx (js/Error. (str "Sorry, no more " item-name))))
Trivial wrapper around [[done!]] Terminate execution of the handler associated w/ the given context, conveying the given error, if non-nil - otherwise mark the execution as failed w/ no specific error. ```clojure (deflambda purchase [item-name ctx] (ctx/fail! ctx (js/Error. (str "Sorry, no more " item-name)))) ```
set-wait-on-event-loop!cljs
(set-wait-on-event-loop! ctx tf)Set the context property callbackWaitsForEmptyEventLoop
Set the context property callbackWaitsForEmptyEventLoop
succeed!cljs
(succeed! ctx & [result])Trivial wrapper around done!
Terminate execution of the handler associated w/ the given context, conveying the given JSON-serializable success value, if non-nil - otherwise mark the execution as successful w/ no specific result.
(deflambda purchase [item-name ctx]
(ctx/succeed! ctx "You bought something"))
Trivial wrapper around [[done!]] Terminate execution of the handler associated w/ the given context, conveying the given JSON-serializable success value, if non-nil - otherwise mark the execution as successful w/ no specific result. ```clojure (deflambda purchase [item-name ctx] (ctx/succeed! ctx "You bought something")) ```
