3 points for using AWS SDK to upload file to S3 bucket
1. onPostBuild method use async method
Gatsby gives plugins and site builders many APIs for building your site. Code in the file gatsby-node.js is run once in the process of building your site.
Pay attention to Async vs. sync work
// Async/await
exports.onPostBuild = async () => {
// do async work
const result = await fetchExternalData()
}
// Promise API
exports.onPostBuild = () => {
return new Promise((resolve, reject) => {
// do async work
})
}2. Create an IAM user to do upload work
Use the Access key ID and Secret access key to construct S3 object, then you can use this S3 object to putObject.
const s3 = new AWS.S3({
signatureVersion: 'v4',
accessKeyId: accessKeyId,
secretAccessKey: secretAccessKeyId,
})For the security, you can use export command to set Access key ID and Secret access key to your local environment variant
export AWS_ACCESS_KEY_ID=YOURACCESSKEYID
export AWS_SECRET_ACCESS_KEY=YOURSECRETACCESSKEY3. Refer to the sdk document
