Global Dependencies

• Node.js

• Rust
• Cargo
• x86_64-unknown-linux-musl (*)
• Docker
• Docker Compose
• AWS CLI

x86_64-unknown-linux-musl Installation

If you are going to build this project locally, in order to build the project properly to use in AWS Lambda, its expected that you install the x86_64-unknown-linux-musl target on all platforms with:

$ rustup target add x86_64-unknown-linux-musl

On Linux platforms, you will need to install musl-tools

On Mac OSX, you will need to install a MUSL cross compilation toolchain:

$ brew install filosottile/musl-cross/musl-cross

Install

In the root of the project, install Node.js dependencies:

yarn

In the functions/api directory, install Rust dependencies (only if you want to modify something on Rust project):

cargo build

Deploy

To configure localstack locally, put this configuration on your ~/.aws/credentials:

[default]
aws_access_key_id = temp
aws_secret_access_key = temp

Get localstack up and running:

yarn docker:up:logs

Use env var DEBUG=1 to see all logs:

DEBUG=1 yarn docker:up:logs

After that, deploy with the command:

yarn deploy:local

Send message

To send message to SQS, first you must get the URL of the queue:

aws --endpoint-url=http://localhost:4566 sqs list-queues

You are going to see two URLs: the SQSHooks and the DeadLetter. Copy the URL of the SQSHooks queue, and execute the following command switching <QUEUE_URL> to URL you got:

aws --endpoint-url=http://localhost:4566 sqs send-message --queue-url <QUEUE_URL> --message-body '{"first_name": "John"}'

You should see the response:

{
    "MD5OfMessageBody": "<SOME_ID>",
    "MessageId": "<SOME_ID>"
}

And in the docker logs, you should see the logs from lambda function:

INFO api: BODY: Body { first_name: "John" }
