Out of memory

[lslocum]

I have a large app I am trying to migrate from Angular 5 to 6 and then to 7. When I try to run rxjs-5-to-6-migrate -p src/tsconfig.app.json I get FATAL ERROR: Ineffective mark-compacts near heap limit Allocation failed - JavaScript heap out of memory. I tried running it with node --max-old-space-size=8192 C:\Users\myName\AppData\Roaming\npm\node_modules\rxjs-tslint\rxjs-5-to-6-migrate.js -p src/tsconfig.app.json and I still get the same error. It seems to "run out of memory" in a matter of seconds, so I suspect there is something else going on. Any help would be appreciated. Thanks!

I'm running into a similar issue. It seems that the migration script shells out to tslint so increasing the memory limit for the script itself doesn't do anything as tslint's memory limit is what needs to be increased.

[tjfryan]

As a workaround, I've cloned the repo, ran npm run release. Went into the dist folder. Ran npm install, then modified 'rxjs-5-to-6-migrate.js' so that it runs tslint via node --max-old-space-size=8192 "node_modules/.bin/tslint" <rest of args> and will let it run with a larger memory limit. Then run the script via <path_to_cloned_repo>/dist/bin/rxjs-5-to-6-migrate -p tsconfig.json. I'm in the middle of running the script and it's gotten further than it did before.

Thanks @tjfryan I don't see where tslint is being used in the rxjs-5-to-5-migrate.js file. What line are you adding this node memory increase?

[tjfryan]

In the file, there is a line that is constructing a shell command from a string. I've changed it to the following:

var command =
    'node --max-old-space-size=8192 ' +
    '"' + path_1.join(__dirname, 'node_modules', '.bin', 'tslint') + '"' +
    ' -c ' +
    '"' + path_1.join(__dirname, 'rxjs-5-to-6-migrate.json') + '"' +
    ' -p ' +
    '"' + optimist_1.argv.p + '"' +
    ' --fix';

Is there any solution to this problem.

@tjfryan can you explain little more clearly please.
