Deploy npm package staticmaps to a nodejs 8.10 lambda in aws.
Because staticmaps depends on sharp to manipulate images, the trick is to have the sharp npm module have the correct
platform files.
I work mainly on windows, so a normal npm install gives me windows related sharp files.
After some struggles, I think these steps were what made my deploy work:
- after a normal
npm install - go into the
node_modulesfolder, locate thesharpfolder, and delete it. - then do
npm install node-gyp --arch=x64 --platform=linux --target=8.10.0 - this will download
sharpwith the correct dependencies to run on lambda node8.10
I started with version 1.8 (at least a year old), and that was giving me deployment issues, so I did npm update serverless -g and that removed my deployment issues when doing sls deploy
To deploy this you should have a recent version of serverless.
In serverless.yml you can give service a different name.
In serverless.yml point provider.profile to your aws credentials.
In serverless.yml use provider.memorySize to make your lambda faster at the expense of possibly increasing your costs if the usage goes over the free-tier limits.
do sls deploy for your initial deploy, the lambda function is created, and the api gateway is created.
After initial deployment, you need to go into the API Gateway settings and tell it to allow binary data responses (images).
In APIG's backend, go to the API's Settings, and a new Binary Media Type. Click on "Add Binary Media Type" and type in */*. Then go to the API Resources, and at the top level, do Deploy API for the settings to take effect.
You can do sls deploy function -f map after initial deploy to avoid all the cloudformation steps and just update the lambda.
