_Build Lambda Layer_ is a utility CLI for building AWS Lambda Layers with control for AWS Node Lambda projects.

---

Why is this written?

_Build Lambda Layer takes complexity out of building lambda layers!_

---

\+ Monorepo support

\+ The ability to ignore and add dependencies at run time

\+ Easy json configuration!

---

How does it does it work?

By running:

``sh
build-layer
`

_Build Lambda Layer_ will:

- install all package.json dependencies to , and
- zip it up to be uploaded to AWS 🚀

---

#### Additionally, _Build Lambda Layer_ works with monorepos!

A key additional feature that Build Lambda Layer provides is that it works with monorepos!

By running:

`sh
build-layer my-lambda-layer --files 'packages/**/package.json'
`

_Build Lambda Layer_ will:

- install all package/**/package.json dependencies to your lambda layer, and
- zip it up to be uploaded to AWS

---

#### Ignore and include the dependencies you want!

_Build Lambda Layer_ supports specificity with ignore and include options.

By adding a "lambdaLayer" object to a package.json file you're building from, you can specify packages to ignore and include:

`json
{
"buildLambda": {
"ignore": ["@types/aws-lambda"],
"include": {
"aws-lambda": "latest"
}
}
}
`

You can also add a lambdaLayerrc file to your project root if you want to preserve your package.json file.

`json
{
"ignore": ["@types/aws-lambda"],
"include": {
"aws-lambda": "latest"
}
}
`

---

#### Be _really_ selective with your installs

There is nothing stopping you from creating your own dependency object to install.

Add a .json file to your project root:

`json
{
"dependencies": {
"aws-lambda": "latest"
}
}
`

And run:

`sh
build-layer my-lambda-layer --files '.json'
`

---

That's it! 🎉

Save yourself the time and effort of building Lambda Layers and let _Build Lambda Layer_ do it for you!
