How to retrieve models/schemas in Lambda/Javascript? about serverless-models-plugin HOT 9 OPEN

For the current version of the models plugin and Serverless this approach should work for your special use case although it is not universal as you can define your models as s-models.json or s-models.yaml.

In future this could even be part of the plugin itself, so that it could generate a validator function/class or provide a way to retrieve the model definitions at runtime. But as I need to do excessive changes for the upcoming Serverless V1, this will not happen in this version.
I will try to keep the model file location the same for Serverless V1 but as things are not yet finalized there, it might still change.

In my case I use only json, so it is quite easy to load the models.

In regards providing validate function as part of the plugin. That depends of what scope this plugin will have in future. So far it is isolated for deploying models to API Gateway, which it does greatly. Doing validations as well would extend its current scope.

Off topic: when is serverless v1 release planned?

from serverless-models-plugin.

Exactly.
They are already working on the new version, but I do not know any date when it will be released,

New obstacle, s-models.json is placed in the root of my project, but Im putting all function code within /function folder, which is also the one being deployed to AWS. This means that I do not have access to s-models.json in function handler when deployed to AWS since it is not bundled within the .zip file. I know I can modify handler path in s-function.json to include all files in the project, but that will increase the total file size.

Is it possible to retrieve models in other way, within the function handler?

from serverless-models-plugin.

Currently not. As a hack you might symlink the s-models.json into your function root.

Could you please be more specific?

from serverless-models-plugin.

Like this

+ s-project.json
+ s-models.json
+ function
   + node_modules
   + s-models.json (symlink to ../s-models.json)

from serverless-models-plugin.

Aah. Thanks. But really an hack, specially when commiting to GIT.

from serverless-models-plugin.

Yes it is :-) But at least GIT handles symlinks correctly.
