What worked for me was `changing single quotes to escaped double quotes`

So from:

    &quot;lint&quot;: &quot;eslint &#39;**/*.{ts,tsx}&#39;&quot;

To:

    &quot;lint&quot;: &quot;eslint \&quot;**/*.{ts,tsx}\&quot;&quot;

The reason is because it depends on the console you are using - possibly the operation system (that&#39;s why it can work for you while it&#39;s not working for others and via versa) Source: https://dev.to/gruckion/comment/b65c

The `--no-error-on-unmatched-pattern` flag was added in `v6.8.0` of ESLint.

Was able to dig up [this closed issue on ESLint&#39;s GitHub](https://github.com/eslint/eslint/issues/10587). Sounds like this is a common problem, and has no good workaround, other than manually checking for the files existence before attempting to lint, as suggested by @user2864740

I have the same error 

&gt; No files matching the pattern **&quot;.ts,&quot;** were found

I just removed spaces between types `.js, .ts, .tsx` in config and it works.

From:

    &quot;lint&quot;: &quot;eslint --ignore-path .gitignore --ext .js, .ts, .tsx .&quot;,

To

     &quot;lint&quot;: &quot;eslint --ignore-path .gitignore --ext .js,.ts,.tsx .&quot;,

In C++ functions, is it a good practice to replace `return` with `throw`? For example, I have the following code

    // return indices of two numbers whose sum is equal to target
    vector&lt;int&gt; twoSum(vector&lt;int&gt;&amp; nums, int target) {
        for(int i=0; i&lt;nums.size()-1; ++i)
            for(int j=i+1; j&lt;nums.size(); ++j)
            {
                if(nums[i] + nums[j] == target) return vector&lt;int&gt;{i, j};
            }
        // return vector&lt;int&gt;{};
        throw &quot;no solution&quot;;
    }

The code above compiles with my GCC 7.2.

I have a field which is a varchar(20)

When this query is executed, it is fast (Uses index seek):

    SELECT * FROM [dbo].[phone] WHERE phone = &#39;5554474477&#39;

But this one is slow (uses index scan).

    SELECT * FROM [dbo].[phone] WHERE phone = N&#39;5554474477&#39;

I am guessing that if I change the field to an nvarchar, then it would use the Index Seek.

Why is query with phone = N&#39;1234&#39; slower than phone = &#39;1234&#39;?

In my CI setup, I have a test that runs eslint against all JS files. If no JS files exist, it&#39;s currently throwing an error. I&#39;d prefer if it&#39;d succeeded when no JS files exist. Is this possible?

```
$ eslint &quot;./src/assets/scripts/**/*.js&quot;

Oops! Something went wrong! :(

ESLint: 5.7.0.
No files matching the pattern &quot;./src/assets/scripts/**/*.js&quot; were found.
Please check for typing mistakes in the pattern.

```

How can I suppress the &quot;No files matching the pattern&quot; message in ESLint?

Trying to use Github&#39;s beta actions, I have two jobs, one that builds the code and then one that will deploy code. However, I can&#39;t seem to get the build artifact in deploy job.

My latest attempt is to manually set a container image with the same volumes for each job, according to docs this should be solution: https://help.github.com/en/articles/workflow-syntax-for-github-actions#jobsjob_idcontainervolumes

&gt; Sets an array of volumes for the container to use. You can use volumes to share data between services or other steps in a job. You can specify named Docker volumes, anonymous Docker volumes, or bind mounts on the host.

**Workflow**

    name: CI
    on:
      push:
        branches:
        - master
        paths:
        - .github/workflows/server.yml
        - server/*
    jobs:
      build:
        runs-on: ubuntu-latest
        container:
          image: docker://node:10
          volumes:
          - /workspace:/github/workspace
        steps:
        - uses: actions/checkout@master
        - run: yarn install
          working-directory: server
        - run: yarn build
          working-directory: server
        - run: yarn test
          working-directory: server
        - run: ls
          working-directory: server
      deploy:
        needs: build
        runs-on: ubuntu-latest
        container:
          image: docker://google/cloud-sdk:latest
          volumes:
          - /workspace:/github/workspace
        steps:
          - uses: actions/checkout@master
          - run: ls
            working-directory: server
          - run: gcloud --version


The first job (build) has a build directory, but when the second job (deploy) runs it doesn&#39;t and only contains the source code.

*This project is a mono repo with code I&#39;m trying to deploy being under path `server` hence all the `working-directory` flags.*

Github actions share workspace/artifacts between jobs?

I&#39;m hoping to get my `pip install` instructions inside my `docker build`s as fast as possible.

I&#39;ve read [many](https://www.aptible.com/documentation/deploy/tutorials/faq/dockerfile-caching/pip-dockerfile-caching.html) [posts](https://vsupalov.com/speed-up-python-docker-image-build/) explaining how adding your `requirements.txt` before the rest of the app helps you take advantage of Docker&#39;s own image cache if your `requirements.txt` hasn&#39;t changed. But this is no help at all when dependencies do change, even slightly.

The next step would be if we could use a consistent pip cache directory. By default, `pip` will cache downloaded packages in `~/.cache/pip` (on Linux), and so if you&#39;re ever installing the same version of a module that has been installed before anywhere on the system, it shouldn&#39;t need to go and download it again, but instead simply use the cached version. If we could leverage a shared cache directory for docker builds, this could help speed up dependency installs a lot.

However, there doesn&#39;t appear to be any simple way to mount a volume while running `docker build`. The build environment seems to be basically impenetrable. I found [one article](https://medium.com/@scythargon/cache-for-python-pip-downloads-and-wheels-in-docker-67f24e7cd84e) suggesting a genius but complex method of running an `rsync` server on the host and then, with a hack inside the build to get the host IP, rsyncing the pip cache in from the host. But I&#39;m not relishing the idea of running an rsync server in Jenkins (which isn&#39;t the most secure platform at the best of times).

Does anyone know if there&#39;s any other way to achieve a shared cache volume more simply?

Using a pip cache directory in docker builds

Is there a way to access the current tag that has been pushed in a Github Action? In CircleCI you can access this value with the `$CIRCLE_TAG` variable.

My Workflow yaml is being triggered by a tag like so:
```
on:
  push:
    tags:
      - &#39;v*.*.*&#39;
```
And I want to use that version number as a file path later on in the workflow.


Dependencies Between Workflows on Github Actions

Normally, my pipelines take 15 minutes to execute. 

Recently, for some strange reasons, some pipelines take between 45 minutes and 6 hours to fail.

Is it possible to set a default timeout limit on GitHub Action&#39;s pipeline (for example, auto cancel after 30 minutes)?

I have this import in my file **app.spec.ts**:

    import app from &#39;./app&#39;;

Which causes this Typescript error

    2:17  error  Unable to resolve path to module &#39;./app&#39;  import/no-unresolved

**./app.ts** does exist, but I have not compiled the .ts file into a .js file. As soon as I compile the .ts file to a .js, the error goes away.

However, since eslint is supposed to work with typescript, it should resolve modules with the .ts and not the .js.

I&#39;ve also added the typescript information in my `eslint` config file:

    &quot;parser&quot;: &quot;@typescript-eslint/parser&quot;,
    &quot;parserOptions&quot;: {
        &quot;project&quot;: &quot;./tsconfig.json&quot;
    }

How can I config eslint in such a way that it tries to resolve modules with the .ts and not the .js?

Cheers!

**EDIT #1**

Content of `app.ts`:

	import bodyParser from &#39;body-parser&#39;;

	import { buildSchema } from &#39;graphql&#39;;

	const app = express();

	const schema = buildSchema(`
		type Query {

	`);
	const root = { hello: () =&gt; &#39;Hello world!&#39; };

	app.use(bodyParser());
	app.use(&#39;/graphql&#39;, graphqlHTTP({

		graphiql: true,
	}));

	export default app;

I installed `jest v24.7.1`in my project with:

    npm install jest -D

Then I start writing some test files, However I got these eslint errors:

    &#39;describe&#39; is not defined. eslint (no-undef)
    &#39;it&#39; is not defined. eslint (no-undef)
    &#39;expect&#39; is not defined. eslint (no-undef)

      extends: [&quot;airbnb&quot;, &quot;prettier&quot;, &quot;prettier/react&quot;],
      globals: {

Should I add another rule or a plugin to fix this?

[`create-react-app` v3.0.0 is out](https://github.com/facebook/create-react-app/blob/master/CHANGELOG.md). It supports TypeScript linting internally. (That&#39;s nice!) I think I understand the situation where TSLint is on, and am planning to replace it with ESLint, but it is not right now.

How to disable that linting step in `react-scripts start`?


`/* eslint-disable */` and others are not the ones I&#39;m looking for.

Disable ESLint that create-react-app provides

With React 16.8.6 (it was good on previous version 16.8.3), I get this error when I attempt to prevent an infinite loop on a fetch request:

```
./src/components/BusinessesList.js
Line 51:  React Hook useEffect has a missing dependency: &#39;fetchBusinesses&#39;.
Either include it or remove the dependency array  react-hooks/exhaustive-deps
```

I&#39;ve been unable to find a solution that stops the infinite loop. I want to stay away from using `useReducer()`.  I did find this discussion *[\[ESLint\] Feedback for &#39;exhaustive-deps&#39; lint rule #14920][1]* where a possible solution is ```You can always // eslint-disable-next-line react-hooks/exhaustive-deps if you think you know what you&#39;re doing.``` I&#39;m not confident in what I&#39;m doing, so I haven&#39;t tried implementing it just yet.

I have this current setup, *https://stackoverflow.com/questions/53243203/react-hook-useeffect-runs-continuously-forever-infinite-loop* and the only comment is about `useCallback()` which I&#39;m not familiar with.

How I&#39;m currently using `useEffect()` (which I only want to run once in the beginning similar to `componentDidMount()`):

```
useEffect(() =&gt; {
    fetchBusinesses();
  }, []);
```

```
const fetchBusinesses = () =&gt; {
    return fetch(&quot;theURL&quot;, {method: &quot;GET&quot;}
    )
      .then(res =&gt; normalizeResponseErrors(res))
      .then(res =&gt; {
        return res.json();
      })
      .then(rcvdBusinesses =&gt; {
        // some stuff
      })
      .catch(err =&gt; {
        // some error handling
      });
  };
```
