Up supports a number of interpreted languages, and virtually any language which can be compiled to a binary such as Golang. Up does its best to provide idiomatic and useful out-of-the-box experiences tailored to each language. Currently first-class support is provided for:
- Golang
- Node.js
- Crystal
- Static sites
When a package.json file is detected, Node.js is the assumed runtime. By default nodejs10.x is used, see Lambda Settings for details.
The build hook becomes:
$ npm run build
The server run by the proxy becomes:
$ npm start
When a main.go file is detected, Golang is the assumed runtime.
The build hook becomes:
$ GOOS=linux GOARCH=amd64 go build -o server *.go
The clean hook becomes:
$ rm server
When a main.cr file is detected, Crystal is the assumed runtime. Note that this runtime requires Docker to be installed.
The build hook becomes:
$ docker run --rm -v $(pwd):/src -w /src crystallang/crystal crystal build -o server main.cr --release --static
The clean hook becomes:
$ rm server
When an index.html file is detected the project is assumed to be static.
