simple-artifact-builder

Easily create deployment artifacts with the minimum set of dependencies required. Tree-shaking made easy.

Purpose

Deployment artifacts can easily get out of hand in size when unnecessary dependencies are included in it. simple-artifact-builder makes it easy to create deployment artifacts with only the dependencies required for your code and nothing more, through file tracing.

Usage

1. install

npm install --save-dev simple-artifact-builder # install it
npx simple-artifact-builder help # and test that you can use it

2. configure

define your artifact.yml config file to specify what files should be included in the artifact with trace (to include it and its traced dependencies) or pick (to just include that file).

for example, for an aws lambda service, you may use something like this:

# artifact.yml
trace:
- dist/contract/handlers/**/*.js # include the handlers of an aws-lambda
- !dist/contract/handlers/**/*.test.js # but make sure to not to include any test files

pick:
- config/*.json # also include the `config` directory, since we dynamically import it

alternatively, if you're deploying a Next.JS project, you may want to use the .nft.json trace output files that they already include. for example:

# artifact.yml
trace:
  - 'dist/server/handler.js' # trace the dependencies of the handler to include the handler and all the code it depends on
  - '.next/**/*.nft.json' # use the trace-output files that next.js automatically generates to include all of the dependencies of the .next server
  - '!.next/cache/**/*.nft.json' # dont use the trace-output files from the .next/cache dir though, as they're not actually defined correctly nor needed

pick:
  - '.next/**/*' # include this whole directory, since the nextjs-server-side-rendering server uses its contents through dynamic imports
  - '!.next/cache/**/*' # exclude the cache though, since that's only needed while compiling and is very large/heavy

3. use

now that you've configured your project's artifact settings, you can build the artifact.

for example, build the artifact into a zip file (e.g., for usage with serverless artifact input)

npx simple-artifact-builder zip

this will output:

.artifact/contents.zip - the zipped up artifact, ready for deployment
.artifact/contents - a directory which hold the contents that were zipped up
.artifact/contents.manifest.json - a file which lists all of the files included in the contents
.artifact/contents.sizes.json - a file which defines the sizes of each file included in the contents
