Including yarn

[nguyenchr]

I saw that you mentioned you were thinking of including in yarn in #71

Just wondering if there has been anymore thought into this?
It would be useful for my particular use case at the moment

Yep – still on the cards. A decent workaround is just downloading it as the first step in your build.

[nguyenchr]

yeah I was thinking that, but my builds are already approaching 5m as it is, for now I'm just using the npm equivalent commands so everything is working dandy 👍

[mhart]

Oh, the downloading would add only literally a couple of seconds to your build – network speed is fast from Lambda – so I wouldn't worry about that aspect.

[mhart]

Going to close this – I think just installing this in your build is the best bet – yarn actually has some issues with disk usage that's made me avoid it on Lambda anyway.

I've had trouble downloading yarn as my first build step using these commands;

FROM lambci/lambda:build-nodejs10.x

ENV AWS_DEFAULT_REGION us-east-1

RUN curl --silent --location https://dl.yarnpkg.com/rpm/yarn.repo |  tee /etc/yum.repos.d/yarn.repo
RUN yum install yarn

COPY . .

Is there a working example that could help guide me?

Use that in a .sh script:

# manual install yarn
curl -o- -L https://yarnpkg.com/install.sh | bash

# enable yarn in cli
export PATH="$HOME/.yarn/bin:$HOME/.config/yarn/global/node_modules/.bin:$PATH"

yarn install
