If a a binary was not available for a given platform and --fallback-to-build was used then node-gyp rebuild will be called to try to source compile the module. It may be that you want to work with two s3 buckets, one for staging and one for production; this arrangement makes it less likely to accidentally overwrite a production binary.
It also allows the production environment to have more restrictive permissions than staging while still enabling publishing when developing and testing. The binary. In order to do so all of the following conditions must be true. If any of these checks fail then the operation will not perform execution time determination of the s3 target. If the command being executed is either "publish" or "unpublish" then the default is set to binary. In all other cases the default is binary.
Node-API is Node runtime engine agnostic and guarantees modules created today will continue to run, without changes, into the future.
Using node-pre-gyp with Node-API projects requires a handful of additional configuration values and imposes some additional requirements. Therefore, an Node-API module must declare in its package. In addition, since multiple builds may be required for a single module, path and file names must be specified in way that avoids naming conflicts.
A Node-API module must declare in its package. This is accomplished by including an napi-versions array property in the binary object. For example:. How this version number is communicated is described next.
Since node-pre-gyp fires off multiple operations for each request, it is essential that path and file names be created in such a way as to avoid collisions. This is accomplished by imposing additional path and file naming requirements.
No problem if it's in both. If Node-API is not supported, this value is an empty string. These values are present for use in the binding. You can host wherever you choose but S3 is cheap, node-pre-gyp publish expects it, and S3 can be integrated well with Travis.
Here is an approach to do this:. And have your key and secret key ready for writing to the bucket. It is recommended to create a IAM user with a policy that only gives permissions to the specific bucket you plan to publish to. It should generate a policy like:.
Appveyor can build binaries and publish the results per commit and supports:. For an example of doing this see node-sqlite3's appveyor. In my case, I use Express and on the client side, I post other data as well so the image has it's own parameter and is accessed as req.

For a smaller file, both methods are fine. In general, I recommend to use upload. In this example, we are using the async readFile function and uploading the file in the callback. As the file is read, the data is converted to a binary format and passed it to the upload Body parameter. To download a file, we can use getObject.
