+**Node.js:** Only [current and LTS](https://nodejs.org/en/about/releases/) Node.js versions are supported. End of life Node.js versions may become incompatible with Marked at any point in time.
+
+**Browser:** Not IE11 :)


@UziTech Makes sense to also document the supported browsers but I can't seem to find them after a bit of light digging. Rollup doesn't seem to be using any specific browserlist for transpiling.

it compiles to es5 but some functions (like startsWith) might need polyfills for browsers that don't include them. Hence the note about IE11.

Let's just link to package.json so that can be the canonical place to determine which Node.js versions are supported.

We should also add this to the docs website, probably after the "Supported Markdown specifications" section.

It might be worth to a set a rule which browsers are supported and to enforce it using https://www.npmjs.com/package/eslint-plugin-compat

I noticed the version in component.json was out of sync. Not sure what this is used for or how it should be updated, but i'm guessing this should be matching the package.json version?

I noticed the version in component.json was out of sync

I'm not even sure what that is for. Looks like it was for something a long time ago. It should probably just be deleted.

Had a little dig a bit further and it's this old tool

Deprecated and dead for quite a few years now

Is this something we can address as part of #2157 before the V3 update? This PR has been open for quite a long time, and seems like this would be the perfect time to either make this change or officially close it out since it relates to semver issues.

UziTech · 2021-08-15T14:38:17Z

We did update engines for v3 in #2157 so the rest of this PR is just docs changes.

calculuschild · 2021-08-15T17:43:39Z

Right. Just saying since we did change engines we might as well finish updating the related docs as part of the same Marked.js release.

UziTech · 2021-08-16T03:24:17Z

Yes @alasdairhurst if you would rebase this we could update the docs.

Thanks for sticking with it! 💯

Only [current and LTS](https://nodejs.org/en/about/releases/) Node.js versions are supported at any point in time.  A drop in support for a Node.js version may not result in a semver major bump to Marked.


I don't think we plan to do this.

We should do semver major when dropping a version of Node.js and bump the engines field

marked/package.json

Line 87 in e781b18

"node": ">= 12"

Would be great if that happened but I wasn't able to convince everyone on the team :)

I may have missed something though. Not been paying too much attention recently and noticed the 3.0.0 release with the documented breaking change dropping node 10.

@styfle Currently we test Node v12, Node lts (v14), and Node latest (v16). When Node LTS changes to v16 we will be testing Node v12, Node lts (v16), and Node latest (v17), so Node v14 will no longer be tested. If we had a team of people working on this every day I think we could task someone with updating that, but realistically there are three-ish people working on marked, whenever we have extra time.

I think it is good to set the expectations low. Ideally we won't break Node versions that aren't tested and we we will only update the engines field on semver major releases but I still like saying, realistically, we could break older node versions in patches since only lts and latest are guaranteed to be tested and the best fix might be for you to update Node.
