Metalsmith plugin for reading/writing/copying files on AWS S3.
Example usage: nonLinear.zone build process.
$ npm install metalsmith-s3
var Metalsmith = require('metalsmith');
var s3 = require('metalsmith-s3');
var metalsmith = new Metalsmith(__dirname)
.use(s3({
action: 'copy',
bucket: 's3-bucket-dest',
from: 's3-bucket-src',
prefix: ['images/', 'js/']
}));
.use(s3({
action: 'read',
bucket: 's3-bucket-src',
ignore: ['images/', 'js/']
}));
...
.use(s3({
action: 'write',
bucket: 's3-bucket-dest'
}));
You can pass through additional settings directly to the s3 library by adding an s3
key and hash.
Properties available vary based on the chosen action:
Example to set the ACL for files written to s3:
var Metalsmith = require('metalsmith');
var s3 = require('metalsmith-s3');
var metalsmith = new Metalsmith(__dirname)
...
.use(s3({
action: 'write',
bucket: 's3-bucket-dest'
s3: {
ACL: 'public-read'
}
}));
If file metadata has an s3
key, it is mixed in as well.
That allows overriding properties on a per-file basis.
Example setting ACL for specific file in front-matter:
---
title: My Article
s3:
ACL: private
---
In case you face the following error, just add the optional parameter region :
TypeError: Error: PermanentRedirect: The bucket you are attempting to access must be addressed using the specified endpoint. Please send all future requests to this endpoint.
Applicable regions are listed in aws documentation.
Usage example:
.use(s3({
action: 'write',
bucket: 's3-bucket-dest',
region: 'eu-west-1'
}));
The read action will read files from an S3 bucket which can then be processed by plugins later in the chain. The read action can be modified to ignore certain prefixes in the S3 bucket be setting the ignore to a prefix, or an array of prefixes.
bucket: source S3 bucket
ignore: a prefix or array of prefixes not to be read from the source S3 bucket
region: bucket's endpoint region (optional)
The copy action will copy files from a source S3 bucket to a destination S3 bucket. The copy action must include a prefix parameter to specifiy one or more prefixes to be processed.
bucket: destination S3 bucket
from: source S3 bucket
prefix: a prefix or array of prefixes to be copied from the source S3 bucket
region: bucket's endpoint region (optional)
The write action will write all files to the destination S3 bucket.
bucket: destination S3 bucket
region: bucket's endpoint region (optional)
Uploaded file's mime type will be set by:
mimeType
property in the file's meta, if set- type determined by mime-type's inspection of the file name
- undefined (interpreted as
application/octet-stream
by S3)
export AWS_ACCESS_KEY_ID='your_access_key'
export AWS_SECRET_ACCESS_KEY='your_secret_key'
Create a credentials file at ~/.aws/credentials
on Mac/Linux or C:\Users\USERNAME\.aws\credentials
on Windows
[default]
aws_access_key_id = your_access_key
aws_secret_access_key = your_secret_key
