Serverless Manifest Plugin

Generate a list of API endpoints, function information & stack outputs to a service manifest file.

The manifest data can be quite useful for:

• Consuming stack values & URLs in frontend applications
• Automatic doc generation
• Saving / sharing values in AWS SSM
• Service discovery

After serverless deploy finishes, a .serverless/manifest.json file, is created.

Usage

Add to plugins array in serverless.yml

service: my-example-service

plugins:
 - serverless-manifest-plugin

Then run serverless manifest --help to see all options.

Options

You can set options via CLI flags or via the custom field in serverless.yml

# Custom settings for manifest plugin
custom:
  manifest:
    # Custom manifest output path. Default ./.serverless/manifest.json
    output: ./serverless.manifest.json
    # set to true to disable manifest file from being created
    disableOutput: false
    # Path to custom file with JS function for additional post processing
    postProcess: ./my-file-to-process-manifest-data.js
    # Set plugin log output to silent. Default false
    silent: false
    # Path to the function code. Default serverless.yml location (process.cwd())
    srcPath: ./dist

plugins:
 - serverless-manifest-plugin

Programatic usage

Using the json flag will pipe the service manifest to stdout. You can use this with a tool like jq to do something programatic with the data.

serverless manifest --json

Example:

serverless manifest --json | jq '.dev.functions'
# Outputs service function info

Generating a manifest file

The plugin will automatically create the manifest when you run serverless deploy

You can also manually generate the manifest at anytime with

serverless manifest

Additionally sls deploy --noDeploy will also generate a manifest file.

Example

Outputs urls, functions, outputs etc.

.serverless/manifest.json
