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

Invoke function

To invoke the function, execute:

yarn serverless invoke -f rust --stage local

You should see the response:

{
  "message": "Hello, world"
}

To pass arguments to the lambda function, run:

yarn serverless invoke -f rust --stage local -d '{"firstName": "John"}'

You should see the response:

{
  "message": "Hello, Jhon"
}
