SyntaxError: Unexpected token function

[olivierperez]

Description

I've made a Docker image to use daggraph without need of npm or any installation (exept Docker of course).

But it failed with this error:

sync function findComponents(projectRootPath){
      ^^^^^^^^

SyntaxError: Unexpected token function

    at Object.runInThisContext (vm.js:97:10)

    at Object.<anonymous> (/usr/local/lib/node_modules/daggraph/src/router.js:7:25)

Steps to reproduce

Here is the command I execute in the root folder of my project:

docker run --rm -v $(pwd):/source olivierperez/daggraph daggraph app/src/

Basically it will execute daggraph app/src/ on my project.

Assumption

I don't use the right folder (in my example: app/src/)

Maybe it can help you, here is the Dockerfile

FROM node:6
RUN npm install -g daggraph
WORKDIR /source

Have you tried to update the node version? Could be a possible cause.

Also how are you handling the input prompted for the graph version type? The cli will ask you for the chart type you want to generate

Yeah, node version. https://stackoverflow.com/questions/37815790/syntaxerror-unexpected-token-function-async-await-nodejs

Thanks, the image now use node:9. It works well 👍
docker run -it --rm -v $(pwd):/source olivierperez/daggraph daggraph .
