s3-frontend-pusher v1.0.4

s3-frontend-pusher

This npm package wipes a specified bucket and pushes contents from a directory provided by a user to aws s3. It is intended to be used with small frontends (read the caveats please) and was motiviated by the fact that we had to install nodejs npm python and awscli in every pipeline thus making required docker build images larger than alpines and taking longer to build in total.

How to use:

1. install the package

npm i -g s3-frontend-pusher

2. use the package in one line

s3-frontend-pusher --key=KEY --secret=SECRET --src=folder --bucket=BUCKET

or create a config file like so:

touch .s3-frontend-pusher

This file needs to be in the folder where you make use of the command. It should be structured in this exact manner:

KEY
SECRET
BUCKET
ENDPOINT
S3FORCEPATHSTYLE

• So line 1 has to be present and it has to be the ACCESS_KEY_ID
• Line 2 has to be present and it has to be the SECRET_KEY
• Line 3 has to be present and it has to be the bucket name
• Line 4 is optional. This is required if you want to do offline uploading against something like localstack or serverless-offline.
• Line 5 is optional. Gets activated only if you put in "true" (without the quotes). This property is required if you want to force the path style. So bucketname.hostname.domain becomes hostname.domain/bucketname. We need to activate this to use localstack. Configurating a different endpoint than the aws requires you to create a config file by the way.

If you have created a .s3-frontend-pusher file you can run the command omitting most parameters:

s3-frontend-pusher --src=folder

CAVEATS

Only works if the bucket content has less than 1000 files. This is due to AWS setting the list-limit to 1000. So there is room for improvement to implement a recursive way to check whether there are still files left inside the bucket or not!

TODOS

• I hate the way we pass the commandline args at the moment and I need to find a shorter way.
• Momentarily uploads happen with ACL: public-read hardcoded. I would like to add plain public to the cli to make this configurable.
